with middleware removed from keystoneclient we no longer need
to keep memorycache around.

oslo-incubator will cease to host common code soon. This is
hopefully the very last sync from oslo-incubator. Sync'ed with

Although a bare docstring is entirely valid grammar, those new to Python find
that pattern baffling, *especially* when other similar methods contain pass
statements. So, for consistency, add a pass statement to otherwise bare
@abc.abstractmethods.

Note that the implementation of an @abc.abstractmethod (in the abstract
base class) can still be called by concrete children, so suddenly
raising a NotImplementedError() instead might be "surprising" to
implementors. A no-op such as "pass" or "return None" is preferable.

Deprecate the apiclient from oslo-incubator so we can get rid of
it.

bp deprecations

Change-Id: I1c761933816da03b6c625f14d0aac43f206e88d7

keystoneclient is using apiclient.base and in order to properly
deprecate and eventually get rid of apiclient we need to move the
symbols that keystoneclient uses out of apiclient.

This change moves apiclient.base.Resource into keystoneclient.base
by merging apiclient.base.Resource into the existing
keystoneclient.base.Resource. apiclient.base.Resource is now
renaming keystoneclient.base.Resource for backwards-compatibility.

Applications are using exceptions out of
keystoneclient.openstack.common.apiclient.exceptions so it's part
of the public interface. But since it's from oslo-incubator it's
not considered stable. Since keystoneclient is all stable this
creates bad situation.

With this change, all the symbols out of apiclient.exceptions are
moved into keystoneclient.exceptions rather than the other way
around (keystoneclient.exceptions used to re-export all of
apiclient.exceptions). Now we're in control of the
apiclient.exceptions and keystoneclient.exceptions that
applications are using.

Some of the docstrings have ``:return:`` instead of ``:returns:``
keyword. This patch fixes that and make it consistent.
