Public bug reported:

In API modules in openstack_dashboard api such as novaclient, neutronclient and so on, API client objects (novaclient, neutronclient...) are created every time openstack_dashboard/api methods are called even in a same request.
Recreating API client object leads to recreating API HTTP connections.

In a same request, API client object should be reused as possible as we
can to reduce the number of connections to backend servers.

Note that keystoneclient in openstack_dashboard/api is the only module
which implements the client object caching.[1]
