* openstack: fix parameter handling when cloud provided as dict
If a cloud is provided as dictionary:
* Do not assert that 'interface' parameter is None. Instead,
assert that it is 'public'.
* Assert that 'auth_type' parameter is not set.
Fixes#42858
* os_user: Include domain parameter in user lookup
If a "domain" parameter is provided, use it in looking up
whether the user already exists.
Fixes#42901
* os_user: Include domain parameter in user deletion
If a "domain" parameter is provided, use it in deleting
the user also.
Fixes#42901
