    Enable custom certificates for keystone communication

    Nova creates a session back to keystone to verify project ids for
    quota and flavor access APIs. The session that was being created was
    not based on conf options, so it only worked in simple default
    scenarios. This updates the session by using the newly added keystone
    section to utilize keystoneauth1 to manage the session creation, which
    allows for specifying custom site certificates to secure the link
    between Nova and Keystone.
