ZhiQiang Fan c612727ff8 use oslo.log instead of oslo-incubator code
oslo.log has graduated from oslo-incubator, and openstack.common.log
has been removed from oslo-incubator, so let's use the new one.

NOTE1:openstack.common.log registers its options at import time, but
oslo.log needs to call register_options() explicitly.

NOTE2: split unit test case in tests/objectstore/test_swift_middleware.py
to avoid duplicate cli option register exception, see NOTE1.
