Previously, updating the quota value for instance on a project that
the user was not currently scoped to would validate the new quota
value by comparing with the usage of the currently scoped project.
The cause of this error was an incorrect use of the server list
parameters.
According to the comment in nova source:
d43d1d6734/nova/api/openstack/compute/servers.py (L277-L280)
and the comments in this bug:
https://bugs.launchpad.net/nova/+bug/1185290
indicate that the tenant_id or project_id flag cannot be used without
the --all-tenants flag.
The fix involves passing the --all-tenants flag when querying instance usage
for any project the user is not currently scoped to. It also removes the
passing of the tenant_id flag when querying the current project.
Tests were also updated to match the new behavior by not passing the
tenant_id to the API call to list servers where the target project is
the currently scoped project.
