Adding configuration to the VIM for containerized keystone. The
VIM will now support two keystone instances:
- platform: bare metal keystone used to authenticate with
platform services (e.g. sysinv, patching)
- openstack: containerized keystone used to authenticate with
openstack services (e.g. nova, neutron, cinder)
For now, the same configuration will be used for both, as we
still only deploy with the baremetal keystone.
