[Sridhar Ramaswamy (srics-r)]

Thanks for picking this one. Trying to assess if this is Mikata or Newton. Is this something we can get it done in next 2-3 weeks ?

    Use oslo log and oslo concurrency

    To make patches small and easy to review, the task (using oslo) is
    implemented in a series of patches.

    In this patch, some codes under tacker/openstack/common are changed
    temporarily, but they will be removed totally in later patches.
