Replace UserManager with None in tests

Don't access keystoneclient's UserManager in tests. This should be
considered private data of keystoneclient and is not actually used by
horizon tests.

    Overriding lbaas.py file and related puppet manifest update for TA2342
    Change-Id: Ifddb4036de15aad50a5ace0693fe297412cc389c

    "The current Horizon Load Balancer VIP input requires a user to input an IP
    address for the VIP on the subnet that the Load Balancer Pool is on.  From
    the CLI or API the neutron lb-vip-create takes a --subnet-id argument.  We
    need an enhancement so that user does not have to manually type in an IP
    from the subnet. Furthermore the neutron lp-pool has a param for subnet-id
    and the VIP gets associated to a pool as an optional param, or from Horizon
    you actually Add Vip under the LB Pool tab which inherently should already
    know what the subnet is. This is an unnecessary hardship for clients and
    prone to race conditions especially on shared networks."
