Magnum has various sections in its configuration file for OpenStack
clients. When internal TLS is enabled, these may need a CA certificate
to be specified.
This change adds a CA certificate configuration, based on
openstack_cacert, for all clients using internal endpoints.
Note: we are explicitly not adding the configuration for the
[magnum_client] ca_file and [drivers] openstack_ca_file options, since
these use the public endpoint by default. These options may be
provided via custom configuration if necessary.
