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.
