    Add admin tenant name to nova notifier

    This change introduces the ability to use the nova admin
    tenant name with the nova notifier in place of the nova
    admin tenant id which may not be available when the neutron
    service is being configured as is the case with tripleo
    installations where the neutron service is configured and
    started before the nova admin tenant has been configured in
    keystone and thus does not have a known id.

    DocImpact
    Introduces the nova_admin_tenant_name configuration entry as
    an optional configurable value in neutron.conf. If the
    nova_admin_tenant_name is configured and the nova_admin_tenanat_id
    is not configured, a performance impact may be seen because
    keystone will become involved in communication between neutron
    and nova.
