Sébastien Han e810d02108 Add radosgw (aka rgw) support 
This patch enables the plugin to setup ceph radosgw and configure
it as a swift-compatible endpoint with keystone integration.

ENABLE_CEPH_RGW is the new variable introduced, which is False
by default, and can be set to True in localrc if radosgw needs
to be setup.

Fixed couple of other (related) things ....
1) Created rgw specific functions
2) Checking for radosgw & swift co-existence, erroring out early enough
3) Using `osd pool default size = 1` in ceph.conf, which set the replica
   size to 1 for all pools as the default

NOTE: Tested on ubuntu trusty only

TODOs ...
1) Not tested on Fedora (F22), radosgw startup has some issues there.

Devstack Ceph Plugin

Overview

Devstack plugin to configure Ceph as the storage backend for openstack services

As part of stack.sh:

  • Installs Ceph (client and server) packages
  • Creates a Ceph cluster for use with openstack services
  • Configures Ceph as the storage backend for Cinder, Cinder Backup, Nova & Glance services
  • (Optionally) Sets up & configures Rados gateway (aka rgw or radosgw) as a Swift endpoint with Keystone integration
    • Set ENABLE_CEPH_RGW=True in your localrc
  • Supports Ceph cluster running local or remote to openstack services

As part of unstack.sh | clean.sh:

  • Tears down the Ceph cluster and its related services

This plugin also gets used to configure Ceph as the storage backend for the upstream Ceph CI job named gate-tempest-dsvm-full-devstack-plugin-ceph

How to use

  • Enable the plugin in localrc:

    enable_plugin devstack-plugin-ceph git://git.openstack.org/openstack/devstack-plugin-ceph

    Note: Ceph can be disabled as the storage backend for a service with the following setting in the localrc file,

    ENABLE_CEPH_$SERVICE=False

    where $SERVICE can be CINDER, C_BAK, GLANCE, or NOVA corresponding to Cinder, Cinder Backup, Glance, and Nova services respectively.

  • Then run stack.sh and wait for the magic to happen :)

TODOs

  • Configuring Rados Gateway with Keystone for Swift
  • Add support for Ceph Infernalis release
  • Add support for distro specific ceph repos
