Import swift3 into swift repo as s3api middleware

This attempts to import openstack/swift3 package into swift upstream
repository, namespace. This is almost simple porting except following items.

1. Rename swift3 namespace to swift.common.middleware.s3api
1.1 Rename also some conflicted class names (e.g. Request/Response)

2. Port unittests to test/unit/s3api dir to be able to run on the gate.

3. Port functests to test/functional/s3api and setup in-process testing

4. Port docs to doc dir, then address the namespace change.

5. Use get_logger() instead of global logger instance

6. Avoid global conf instance

Ex. fix various minor issue on those steps (e.g. packages, dependencies,
  deprecated things)

The details and patch references in the work on feature/s3api are listed
at https://trello.com/b/ZloaZ23t/s3api (completed board)

Note that, because this is just a porting, no new feature is developed since
the last swift3 release, and in the future work, Swift upstream may continue
to work on remaining items for further improvements and the best compatibility
of Amazon S3. Please read the new docs for your deployment and keep track to
know what would be changed in the future releases.
