Zuul3-related changes in master have moved functional test gate
configuration out of infra/project-config and into the glanceclient
repository.  This patch backports these changes so that the stable
branch has functional test gates.

Not a pure cherry-pick, also includes setting SWIFT_HASH, which
did not have to be done in master.

CLI image-create-via-import fails with ValueError. The reason
is create command returns RequestIdWrapper object and not image
and response.

Further it fails with AttributeError: 'Namespace' object has
no attribute 'import_method'. The reason is do_import_image() call
requires 'import_method' as input which is not provided at the
moment.

image-stage call fails with TypeError saying 'stage() takes exactly
3 arguments (4 given). The reason is stage() also accepts image_size
as a argument which is not provided.

Further it raises 'NoneType' object has no attribute 'headers'. The
reason is stage() internally calls upload method which
returns a object of RequestIdWrapper on body (which is None) and
response. In stage call it again tries to add request id which requires
response object but instead it has a RequestIdWrapper which fails to
retrieve headers.
