Allow admin's to modify image members.

Updates the v1 Glance API and Registry controllers so that admins
can modify image membership regardless of image ownership.

The motivation for this change is to be able to test image membership
when noauth middleware (UnauthenticatedContextMiddleware or
FakeAuthMiddleware) is being used and includes the following changes:

 * Added is_admin option to FakeAuthMiddleware.

 * Refactors the access checks into a common function called
   _check_can_access_image_members.

 * API unit tests which require is_admin=False for noauth were also
   refactored to use an improved FakeAuthMiddleware which supports
   is_admin = False.

 * Update RegistryClient to use get_status_code int for 204 status code
   comparisons. Fixes issue where incorrect status code was returned.

 * Updated members unit tests to support these changes.

Fixes LP Bug #1021740.

Keystone dep is not actually needed.

An end user might need to install keystone to use the default config,
but glance testing uses stubbed out fakes.

Remove microseconds before time format conversion.

Updates Glance scrubber so that it chops microseconds off of the
date format before parsing a time format string. This fixes
an exceptions that can occur when using scrubber with databases
like PostgreSQL which include microseconds in date strings.
