Sync with oslo-incubator 2fd457b

This syncs Keystone with oslo-incubator commit hash
2fd457bf2ccbeb2b84ffb204778b6417cd5405ba .

In keystone:

 $ rm -r keystone/openstack/common

In oslo-incubator:

 $ python update.py ../keystone

The newer lockutils requires posix_ipc. It's already in
global-requirements.

Keystone uses gettextutils and versionutils from oslo-incubator
so those should be in openstack-common.conf. They were pulled in
as dependencies of other oslo-incubator modules but Keystone
shouldn't rely on that.

Keystone doesn't use log_handler directly so that module was
removed from openstack-common.conf. log_handler is available in
the oslo.messaging library.
