Add a generic retry decorator to cinder/utils
Retries are something that we use in a number of
places, and could probably use in a few more. Rather
than continue writing custom retry code or silly loops
let's add a generic retry decorator class that can be
initialized and used as needed.
This patch leverages the retrying library that's already
in OpenStack Requirements and used in other places. We
just add a wrapper around it for some logging and add
a bit of error handling incase somebody sets retries to 0

Submitted a retry decorator and it was pointed out that
the retrying library was already in global-requirements,
it would probably be good to leverage this and use it rather
than roll our own, so let's add it to our version of requirements
and then we can look at whether using a decorator or just
leveraging the lib is the right way to go.

The cloned volume size is wrong when the size is different

Ensure lazy translation is disabled properly
Commit 894f20d9cf57b36ccf9a675c6b2b070d56c9b297 changed the way that
enable_lazy() is being configured in cinder's test cases. The changes
were required to remove the use of _lazy from the oslo's i18n library.
_lazy was removed from i18n and the code that was accessing the internal
variable broke. The commit referenced above made changes to remove
the use of _lazy.
The commit, however, changed the behavior of the test cases to only
enable_lazy without disabling it, which diverges from the original
behavior.
This commit uses the new oslo.i18n ToggleLazy fixture (added in 1.3.0).

new connection initialization in cinder/volume/targets/tgt.py).
2. The iSER and iSCSI prefixes equalized, due to the removal of brick/iscsi
