Handle IPv6 specifid glance servers gracefully

IPv6 netlocs can for valid reasons contain ':', so
splitting by ':' is dangerous. Instead of splitting
by host and port in order to only reassemble it into
a netloc again later, simply always pass netloc, which
avoids the bug.

Add extra textcases to verify the new behavior.
Fix Flake8 warnings.

Re-write of the cinder-manage man page.

The cinder-manage man page didn't appear to have been re-written
since splitting from Nova.  There were numerous options that
no longer exist documented and references to Nova instead of
Cinder.

This version has been re-written based on the current code in
cinder-manage.

Elevate acceptors context on accept reserve udpate

When accepting a transfer we need to update the
quota data for both the donor and the acceptor's.
The acceptor is easy enough (as that's the context
we currently are using) however to update the donor's
quota data we need an elevated context.
