    Synchronising oslo-incubator service module

    Importing service module and its dependencies to enable
    openstack common service launcher within glance. This will
    be used as the framework for event notifiers and listeners.

    This change is a pre-requisite for blueprint
    catalog-index-service implementation

    All imported modules are new and shouldn't impact any of
    the existing glance functionality.

    Closes-Bug: #1413861
    Partially Implements: blueprint catalog-index-service
