Ian Cordasco c3baf74f26 Update sample config files for Ocata-3 
In preparation for the last Ocata beta milestone, let's update our
configuration files. This will also allow for other folks who are
updating config files to create much smaller diffs.

#
# Allow users to add additional/custom properties to images.
#
# Glance defines a standard set of properties (in its schema) that
# appear on every image. These properties are also known as
# ``base properties``. In addition to these properties, Glance
# allows users to add custom properties to images. These are known
# as ``additional properties``.
#
# By default, this configuration option is set to ``True`` and users
# are allowed to add additional properties. The number of additional
# properties that can be added to an image can be controlled via
# ``image_property_quota`` configuration option.
#
# Possible values:
# * True
# * False
#
# Related options:
# * image_property_quota

# (boolean value)
#allow_additional_image_properties = true

#
# Maximum number of properties allowed on an image.
#
# This enforces an upper limit on the number of additional properties an image

# Python module path of data access API.
#
# Specifies the path to the API to use for accessing the data model.
# This option determines how the image catalog data will be accessed.
#
# Possible values:
# * glance.db.sqlalchemy.api
# * glance.db.registry.api
# * glance.db.simple.api
#
# If this option is set to ``glance.db.sqlalchemy.api`` then the image
# catalog data is stored in and read from the database via the
# SQLAlchemy Core and ORM APIs.
#
# Setting this option to ``glance.db.registry.api`` will force all
# database access requests to be routed through the Registry service.
# This avoids data access from the Glance API nodes for an added layer
# of security, scalability and manageability.
#
# NOTE: In v2 OpenStack Images API, the registry service is optional.
# In order to use the Registry API in v2, the option
# ``enable_v2_registry`` must be set to ``True``.
#
# Finally, when this configuration option is set to
# ``glance.db.simple.api``, image catalog data is stored in and read
# from an in-memory data structure. This is primarily used for testing.

# The default number of results to return for a request.
#
# Responses to certain API requests, like list images, may return
# multiple items. The number of results returned can be explicitly
# controlled by specifying the ``limit`` parameter in the API request.
# However, if a ``limit`` parameter is not specified, this
# configuration value will be used as the default number of results to
# be returned for any API request.
#
# NOTES:
# * The value of this configuration option may not be greater than
# the value specified by ``api_limit_max``.
# * Setting this to a very large value may slow down database

# Maximum number of results that could be returned by a request.
#
# As described in the help text of ``limit_param_default``, some

# returned are governed either by the ``limit`` parameter in the
# request or the ``limit_param_default`` configuration option.
# The value in either case, can't be greater than the absolute maximum
# defined by this configuration option. Anything greater than this
# value is trimmed down to the maximum value defined here.

# Show direct image location when returning an image.
#
# This configuration option indicates whether to show the direct image
# location when returning image details to the user. The direct image
# location is where the image data is stored in backend storage. This
# image location is shown under the image property ``direct_url``.
#
# When multiple image locations exist for an image, the best location

#
# NOTES:
# * Revealing image locations can present a GRAVE SECURITY RISK as

# Please see the Newton release notes for more information.

# Maximum size of image a user can upload in bytes.

#
# NOTES:

#
# * If this option is disabled, then the ``enable_v1_registry``

#
# The driver to use for image cache management.
#
# This configuration option provides the flexibility to choose between the
# different image-cache drivers available. An image-cache driver is responsible
# for providing the essential functions of image-cache like write images to/read
# images from cache, track age and usage of cached images, provide a list of
# cached images, fetch size of the cache, queue images for caching and clean up
# the cache, etc.
#
# The essential functions of a driver are defined in the base class
# ``glance.image_cache.drivers.base.Driver``. All image-cache drivers (existing
# and prospective) must implement this interface. Currently available drivers
# are ``sqlite`` and ``xattr``. These drivers primarily differ in the way they
# store the information about cached images:
# * The ``sqlite`` driver uses a sqlite database (which sits on every glance
# node locally) to track the usage of cached images.
# * The ``xattr`` driver uses the extended attributes of files to store this
# information. It also requires a filesystem that sets ``atime`` on the
# files
# when accessed.
#
# Possible values:
# * sqlite
# * xattr
#
# Related options:

# Allowed values: sqlite, xattr

#
# The upper limit on cache size, in bytes, after which the cache-pruner cleans
# up the image cache.
#
# NOTE: This is just a threshold for cache-pruner to act upon. It is NOT a
# hard limit beyond which the image cache would never grow. In fact, depending
# on how often the cache-pruner runs and how quickly the cache fills, the image
# cache can far exceed the size specified here very easily. Hence, care must be
# taken to appropriately schedule the cache-pruner and in setting this limit.
#
# Glance caches an image when it is downloaded. Consequently, the size of the
# image cache grows over time as the number of downloads increases. To keep the
# cache size from becoming unmanageable, it is recommended to run the
# cache-pruner as a periodic task. When the cache pruner is kicked off, it
# compares the current size of image cache and triggers a cleanup if the image
# cache grew beyond the size specified here. After the cleanup, the size of
# cache is less than or equal to size specified here.

# description of configuration option ``image_cache_dir`` for more detail.
# Sometimes, due to various reasons, it is possible the download may hang and
# the incompletely downloaded image remains in the ``incomplete`` directory.
# This configuration option sets a time limit on how long the incomplete images
# should remain in the ``incomplete`` directory before they are cleaned up.
# Once an incomplete image spends more time than is specified here, it'll be
# removed by cache-cleaner on its next run.
#
# It is recommended to run cache-cleaner as a periodic task on the Glance API
# nodes to keep the incomplete images from occupying disk space.

#
# Base directory for image cache.
#
# This is the location where image data is cached and served out of. All cached
# images are stored directly under this directory. This directory also contains
# three subdirectories, namely, ``incomplete``, ``invalid`` and ``queue``.
#
# The ``incomplete`` subdirectory is the staging area for downloading images. An
# image is first downloaded to this directory. When the image download is
# successful it is moved to the base directory. However, if the download fails,
# the partially downloaded image file is moved to the ``invalid`` subdirectory.
#
# The ``queue``subdirectory is used for queuing images for download. This is
# used primarily by the cache-prefetcher, which can be scheduled as a periodic
# task like cache-pruner and cache-cleaner, to cache images ahead of their
# usage.
# Upon receiving the request to cache an image, Glance touches a file in the
# ``queue`` directory with the image id as the file name. The cache-prefetcher,
# when running, polls for the files in ``queue`` directory and starts
# downloading them in the order they were created. When the download is
# successful, the zero-sized file is deleted from the ``queue`` directory.
# If the download fails, the zero-sized file remains and it'll be retried the
# next time cache-prefetcher runs.

# set for this configuration option with the first N chars of the image UUID

#
# Example: if the seed is set to 3 and swift_store_container = ``glance``, then
# an image with UUID ``fdae39a1-bac5-4238-aba4-69bcc726e848`` would be placed in
# the container ``glance_fda``. All dashes in the UUID are included when
