[autotest] Establish a common interface for host representation.
This cl has the work needed to ensure that schema changes made on
the server trickled down into the client. If the same changes don't
reflect on the client, creating or saving a client host wrapper for
a given host will fail deterministically on the client side until
modules using the rdb_host are modified to reflect the changes.
1. rdb_hosts: A module containing the host heirarchy needed to
establish a dependence between the creation of the RDBServerHostWrapper
(which is serialized and returned to the client, which converts it
into an RDBClientHostWrapper) and the saving of the RDBClientHostWrapper
through and rdb update request.
2. rdb_requests: Contains the requests/request managers that were in
rdb_utils, because I plan to expand them in subsequent cls.
3. rdb_model_extensions: Contains model classes common
to both server and client that help in establishing
the common host model interface.
4. rdb integration tests.
