Avoid dangling partial image on size/checksum mismatch

Fixes bug 1122299

Previously, when the supplied image size or checksum didn't match
the calculated values, partial image image data was left dangling
in the backend store.

Now, we clean up when the mismatch is detected.

Clean dangling image fragments in filesystem store

Fixes bug LP 1104924

Previously when a PUT or POST of image content was terminated
prematurely by the client, the partially saved image file was
left behind in the data directory.

Swallow UserWarning from glance-cache-manage

Fixes bug 1129445

Previously, we exposed internal technical debt as an apparent
user-facing warning.

Now the warning is swallowed in the internal case, but continues
to be seen by external users of this library.

Note that this fix is not relevant on master, as that the warning
no longer occurs in that case.

Wait in TestBinGlance.test_update_copying_from until image is active

Test randomly fails on slow machines, the updated image is still
in 'Status: saving' while 'Status: active' is expected. So loop around
the "glance show" command until the image leaves the 'saving' state
(bug 1107768).

Prints list-cached dates in isoformat

Converts dates printed by list-cached to a human readable format
(isoformat). It now checks whether the image last_access time is == 0.0
and prints "Not Accessed Yet" if so.

* Updates openstack.common.timeutils
* Fixes bug 1102334

Do not return location in headers

In some cases credentials were being leaked when downloading a cached
v1 image.

Ensure repeated member deletion fails with 404

Fixes bug 1157427

If an image membership is deleted more than once, the second and
subsequent deletions would be expected to return a 404 Not Found
response code, as opposed to 204 No Content.

Previously, the can_show_deleted logic got in the way, such that
for an admin caller the previously deleted membership was considered
still extant.

We now override the show_deleted logic for deletion, as it makes no
sense to consider the existence of previously deleted database rows
when another deletion request is issued.

Note that there is no corresponding proposal to master as this logic
has been refactored and this no longer affects master.

Check if creds are present and not None

Currently, KeystoneStrategy checks whether the required credentials are
present in the creds dict but it doesn't check whether they are valid or
not.

This patch checks whether the required creds are present and not None
otherwise a MissingCredentials exception will be raised.

Note: No need for checking parameters' values types since they'll be
instances of basestring once set otherwise they'll be None.
