The --project option of 'openstack keypair list' is supposed to filter
keypairs by a project but has not been working and instead returns
keypairs from all projects.
The reason appears to be because it uses a request for a user list
filtered by project but tenant_id/project_id is not a valid filter for
GET /users.
This fixes the issue by requesting role assignments for the specified
project and then requesting keypairs for users with a role in the
project.
This change depends on a recent openstacksdk bug fix change
Ic552dee83d56278d2b866de0cb365a0c394fe26a which fixed the user_id query
parameter for the compute /os-keypairs APIs. The bug fix was released in
openstacksdk 4.4.0.
