Adds some easy-of-use for openstack mock tests
JCLOUDS-400: Allow the HeaderParam annotation to be used in a Caller.

This allows jclouds to factor out common headers into the Caller so they don't
have to be repeated in the Callee.

The Produces/Consumes annotations (Content-Type/Accept headers) will also
propagate from the Caller to the Callee.

JCLOUDS-410. Deprecate Payload.getInput

We plan to transition Payload to ByteSource in the next major release.
Unfortunately Payload.getInput masks its checked exception and
ByteSource.getInput is final so we cannot continue to mask the
exceptions.  Deprecation of getInput and addition openStream allows us
to transition callers from the former to the latter.
