Attempt to ensure connect always timesout

It seems that the test_connect_put_timeout() test does not always fail
when it is expected. Sometimes, not very often, the attempt to connect
succeeds, resulting in a failed test.

This might be because the fake-connection infrastructure uses a
sleep(0.1) and the test uses a connect timeout of 0.1. There might be a
case where the two values result in the exact time where the entries
happen to be added in the wrong order such that the sleep() completes
first before the connect timeout fires, where the connect completes
successfully.

Support for content-length in the upload object method for
internal client.

Internal client uses 'chunked' transfer encoding in it's
upload_object method. If content-length is known in advance,
internal_client should allowed to use content length in the
upload_object method and not the chunked method.

Unify backend logging

Make account, object, and container servers construct log lines using the
same utility function so they will produce identically formatted lines.

This change reorders the fields logged for the account server.

This change also adds the "additional info" field to the two servers that
didn't log that field.  This makes the log lines identical across all 3
servers.  If people don't like that, I can take that out.  I think it makes
the documentation, parsing of the log lines, and the code a tad cleaner.

Add missing constraints to /info

Two of the default constraints, max_header_size and
max_meta_overall_size, don't get registered for the
/info response by the proxy server.

Rather than adding them individually to the proxy's
register_swift_info call, this patch proposes to
register all the constraints for /info at once
using the constraints.EFFECTIVE_CONSTRAINTS dict.
Any future additions to default constraints will
then be automatically included in /info.

update setup.py with pbr version

This file is normally updated in the standard "update from
global requirements" patch, but since those contain other
changes we don't want, the setup.py file never gets updated.

This patch updates setup.py to bring it in line with the
standard global requirements way of doing things without also
updating [test-]requirements.txt

Fix deprecation warning

Accessing BaseException.message spews a warning; we can get the same
information with str(err), which does not spew.

Add tests and comments re constraints in /info

Add test to check that only the expected keys are
reported by proxy in /info, and add comments to
raise awareness that default constraints will be
automatically published by proxy in response to /info
requests.
