The current code builds a full object listing before performing either a multiple
download or delete operation (and also shuffles this complete list in the case of
a download). This patch removes the creation of the full object list and adds the
ability to turn off shuffle for files when downloading. Also added is a limit on
the number of list results that can be queued by a single call to service.list
without consuming results (reduces memory overhead for large listings).
Some tests added for service.py download and list.

This patch adds "--output-dir" and "--remove-prefix" options
to the "download" command and unit tests for it.
Example:
$ swift list example --prefix swift2.2
swift2.2/bin/swift-object-auditor
swift2.2/bin/swift-object-expirer
swift2.2/bin/swift-object-info
swift2.2/bin/swift-object-replicator
swift2.2/bin/swift-object-server
swift2.2/bin/swift-object-updater
When given "--output-dir <directory>", client downloads objects to <directory>.
$ swift download example --prefix swift2.2 \
--output-dir new/swift/dir
The folder structure:
.
└── new
└── swift
└── dir
└── swift2.2
└── bin
├── swift-object-auditor
├── swift-object-expirer
├── swift-object-info
├── swift-object-replicator
├── swift-object-server
└── swift-object-updater
When given "--remove-prefix", client downloads objects without <prefix>.
$ swift download example --prefix swift2.2 \
--remove-prefix \
--output-dir swift
The folder structure:
.
└── swift
└── bin
├── swift-object-auditor
├── swift-object-expirer
├── swift-object-info
├── swift-object-replicator
├── swift-object-server

There was always an implicit assumption that they were UTF-8 before, and
by converting them to unicode we close another hole allowing raw bytes
to appear in user-facing messages.

Currently SwiftClient populate response dictionary before
removing "./" or "/" at begining of object name. This patch
fixes that by changing that order.

Setting timeout to a default of False in get_auth()
results in a requests timeout of 0.0 in keystoneclient,
which causes a connection failure.
This bug will cause func tests to not run when using
keystoneauth.
Added unit tests to verify correct default timeout is set
in get_auth().
Drive-by: remove what seems like a stale TODO comment

This allows the use of --skip-identical when downloading SLOs and DLOs,
while still only requiring one request for normal objects.

Previously, we had urllib3 (via requests) automatically decode all
responses with a Content-Encoding of deflate or gzip. This included
object downloads, which would in turn cause etag or content-length
mismatch errors. (See bug 1338464)
This was apparently added in response to a third-party proxy sitting
between the client and server which, having observed that the client
would accept gzip-encoded content while the server sent an unencoded
response, would perform the compression. (See bug 1282861)
Now, we'll no longer let requests send any default headers, nor do any
decoding.

The underlying requests library supports a timeout input parameter. The
other python-*client libraries support passing it in, so while working
on shade, it seemed like a great idea to be able to pass in timeout to
swiftclient too. For reference, there's a change in shade:
I095c1240693abf024bda2315dd77f4400b24a45b that shows interaction with
the other libs, and a tentative patch that would consume this one.

Currently, get_object returns a generator. This allows access to the
object's data in multiples of 'resp_chunk_size'.
This patch adds a read function to also allow accessing the object data
using read(size).
This allows, for example, the consumer of an object (where no byte range
has been specified) to read up to certain boundaries while streaming to
a new Large Object with segments of a specified size.
Reading and chunking can be safely mixed.

Previously, we compared the ETag from Swift against the MD5 of the
entire large object. However, the ETag for large objects is generally
the MD5 of the concatenation of the ETags for each segment, unless the
object is a DLO whose segments span more than one page of a container
listing. Rather than worry about ETags, just compare each chunk of the
segmented file. This allows the use of --skip-identical when uploading
SLOs and DLOs.
Additionally, there are several test-related improvements:
* The default arguments for OutputManager are now evaluated on
construction, rather than on definition, so that
TestOutputManager.test_instantiation will succeed when using nosetest
as a test runner. (See also: bug 1251507)
* An account_username option is now available in the functional tests
config file for auth systems that do not follow the account:username
format.
* CaptureOutput no longer writes to the captured stream, and
MockHttpTest now captures output. These were polluting test output
unnecessarily. (See also: bug 1201376)

Previously, only the first container-listing's worth of segments was
deleted, which would leave behind orphaned segments when the object was
very large with small segments or the server's container_listing_limit
was small.
In addition, process DLO and SLO deletions on the segment thread pool,
rather than the object thread pool.

Previously, it would only output something like
ClientException: Object PUT failed <url> 413 Request Entity Too Large
Your request is too large.
... which is misleading as it implies that Swift simply can't handle
large objects.

With MD5Sum checking being added, a concern was brought up that It was
a change with no possibility of reverting to the old behaviour.
This change adds the flag '--ignore-checksum' to the upload subcommand
allowing the checks to be turned off.
Changed occurrences of the magic string for a null md5 to use a descriptive
constant instead.
Updated Error messages generated when validation fails. They should now be more descriptive
and not output a literal newline sequence.

The chunk looks like nicely containable, but it pushes against the
right edge of the screen annoyingly. This patch _only_ prettifies,
without any observable changes.

When using stream=True, we need to make sure we release a connection
back to the connection pool to avoid warnings clogging up the logs. We
can do this by releasing the connection once we've read all the content
from the response. In situations where stream=False, requests already
does this for us.
