This operation is undefined in Python3, list() must be called first.

Only call decode() on bytes

In Python 3, text strings are not bytes, so the decode() method should not be
called on them.

REST method to fetch deployments metadata for a server

This REST method returns a grouped collection of deployment resource
metadata which a server uses as its configuration inputs.

Previously the index method was overloaded to perform this function too.

Currently this will be called by heat-engine when the server
resource metadata is polled, but it should eventually be possible
for servers to call this method directly so that a stack does not
need to be parsed every time a server polls for metadata.
