During some runs of functional testing, swift global replication would
only have 2 copies rather than 3 of the object that was just written.
This patch attempts to resolve the race condition and also adds ordering
to more recently added tests.
Closes-Bug: #1882247
The SwiftImageCreateTest was running a pause/resume test for
swift proxy which does not make sense. So, break the proxy specific
tests into their own class and add a class for storage. A
subsequent change to the swift-proxy charm will be needed to add
the new proxy test class to the tests.yaml.
