JCLOUDS-567: Upgrade Apache HttpClient to 4.3.4
Remove ByteSources.asByteSource

This method breaks the contract of ByteSource which specifies that
openStream can produce multiple independent streams.
Add symbolic error codes for Atmos
Add deleteContainerIfEmpty to BlobStore

This matches how most blobstores operate: delete container is a single
operation, not a compound operation which recursively deletes blobs.
Azure is the only provider which allows deleting a non-empty
container.
Allow Javadoc to reference imports

These style errors continue to creep in due to IDE misconfiguration so
we might as well stop checking for it.
Remove loop to gather metrics

This loop dramatically increases integration test run-time for no
discernible benefit.
Try iso8601SecondsDateParse if iso8601DateParse fails.

S3 compatible blobStores sometimes return date in the format:
"2014-07-23T20:53:17+0000" instead of the more common
"2014-07-23T18:09:39.944Z". This caused jclouds to barf with an
IllegalArgumentException.

This commit tries to parse both the formats for S3. The exception
is thrown if both fail.

Added unit tests for the same.
Handle possibly null message from IOException
Correct comment
'iso8601DateParseWithOptionalTZ' -> 'iso8601DateOrSecondsDateParse' in DateService

JCLOUDS-646: Copied Cloud Identity v1.1 classes from openstack-common and fixed incorrect Keystone package names
Introduce BlobstoreCli

This commit provides an alternative and lighter-weight way to interact
with blobstores from the command-line.  The really-executable-jar is 6
MB instead of jclouds-cli 30 MB and starts up in 2.5 vs. 3.0 seconds.
Further it gives better control over configuration and logging.
