[keystone] Federated users who wish to use CLI

Have you tested the OpenStack CLI with v3oidcpassword or v3oidcauthcode and
multiple IdPs configured in Keystone?
We are currently debugging and discussing on how to enable this support in
the CLI. So far, we were not able to make it work with the current code.
This also happens with Horizon. If one has multiple IdPs in Keystone, the
"discovery" process would happen twice, one in Horizon and another in
Keystone, which is executed by the OIDC plugin in the HTTPD. We already
fixed the Horizon issue, but the CLI we are still investigating, and we
suspect that is probably the same problem.
