heat cli : Rework to separate cli tool from client-API wrappers
Rework to remove duplication between heat and heat-boto, and to provide better separation between the CLI tool logic and the underlying client API (should allow easier porting to new ReST API) Ref #175 (partially fixes) Fixes #192 Change-Id: Ib1f821667c40c78770a345204af923163daeffae Signed-off-by: Steven Hardy <shardy@redhat.com>
