Deprecate is_admin feature.

- This has been confusing since the beginning of keystoneauth.
- Do not remove the feature but just print a large warning when
  used.

Made internal client handle failed requests better

In two places, the internal client was not doing what it should with failed requests.

Change the flag set to specify bulk delete and expand archives from a HTTP
header to a query parameter.

This is needed because query parameters show up in proxy logs and headers do
not. With this change it will be easy to determine from any log line that gets
created from the original request (of which there is currently none) that the
request was a bulk action.

Note: This is not backwards compatible with the previous method of setting a
header. Because the bulk middleware has not been included in an openstack swift
release this should be fine.
