Since all params of quota update command are optional (except
project_id), when no quota field is supplied the command shouldn't
execute successfully.
This patch shows an error in this case.

Upload-to-image would error after launching
the operation if the volume type is None.

Closes-Bug: #1821818
Change-Id: I015e0ddfa98d62f25334e2df5effaee72a3988ab

The output of upload-to-image is not readable due to
volume type is printed in output as a whole.
Printing volume type name only cleans up the output.

Enforce ordering of imports with H306.

For tests, this is mostly done by grouping test
imports after other cinderclient imports.

Added missing column 'Allocated' for
quota usage command.

Change-Id: Ic2656e2f849e834c7a576b0462d6e8a399a95006

Usage: It adds an optional argument --poll to the cinder
create command which waits while the creation of the volume
is completed and the volume goes to available state. In case
there is an error in volume creation, it throws an error message
and exits with a non zero status. The error message printed here
is the async error message in case it generates one.

Support skip-validation parameter for quota update.

Change-Id: Iec4f1598987c632f45ad6eee751f78bedbf3ec26

Cinder doesn't support to update consistencygroup quota. And
since cg will be deprecated in Queue, there is no value to support it
at server or client side. So this patch removed it.
