This change adds SAML2 support through the use of a new keystone SAML
integrator charm (keystone-saml-k8s).
Needed changes have also been made in the keystone charm to make use of
the new relation.
A new option has also been added to keystone-k8s through which a secret
can be specified which should contain the x509 certificate an the
corresponding key from which it was derived, used to generate the keystone
SP metadata file.
