Attempt to make test_memcache_pool_timeout stable

Too much time can pass after we create a set of co-routines and when
the parent co-routine continues is setup and staging. Instead, we
perform all the setup and staging, let the system run and then verify
the final state after all the dust settles.

Remove swiftclient dependency

Removes the requirement for swiftclient in swift-dispersion-report
and swift-dispersion-populate. To prevent a dependency on
keystoneclient and to avoid reinventing the wheel with an internal
keystoneclient, authentication with keystone is only supported if
swiftclient is available. If not, only auth v1 is supported.

The dependency in swift/container/sync.py has also been removed.

Implements: blueprint remove-swiftclient-dependency

Ensure swift.source is set for DLO/SLO requests

SLO was setting it sometimes (the PUT path), but not others (the GET
path), and DLO just wasn't doing it at all. One could already
distinguish DLO/SLO internal requests by the user agent, but we should
set swift.source too.

Don't create bin/* files magically

Just use import to make scripts available in bin/ instead of
creating these during setup.py install.
