    Fix a swact issue on system controller

    The swact operations failed few times due to dcorch-engine not
    being enabled. At the startup, the dcorch-engine starts the
    QuotaManager, which tries to open keystone client session
    against the keystone-api-proxy. At this time,
    the keystone-api-proxy is not yet running.

    This dependency is introduced by an incorrect region name used
    in the class EndpointCache. The default keystone client session
    should be opened against the keystone in RegionOne.
    The dcorch-engine enabling process, has a dependency on keystone
    which enables keystone first.

    This update corrects the region name in EndpointCache.
