openstack.common needs to be synced and unused module should be removed

[Akihiro Motoki]

Most modules in openstack_dashboard/openstack/common are out-of-date and need to be synced with latest oslo.
The following modules are out-of-date.

In addition, many modules are not used in OpenStack Dashboard. If I remember correctly, they were introduced because of third-party integration but if it is required in third-party implementation they should import oslo in their tree not in the upstream.
Note that notifier and rpc in oslo now graduated oslo-incubator and maintained as separate module (oslo.messaging).
Use of oslo-incubator rpc and oslo is deprecated.
IMO they should be removed from horizon tree from the maitenance perspective before Icehouse release.

- context
- eventlet_backdoor
- loopingcall
- network_utils
- notifier/*
- rpc/*
- service
- threadgroup
- uuidutils

    They are not used in horizon code base and out-of-date for a long time.
    It is time to remove them.
    - notifier and rpc graduated oslo-incubator and are distirubted as a
      separate module (oslo.messaging).
    - uuidutils is now deprecated in oslo and standard uuid module is
      recommended to use.
