> Although the previous approach was corrrect technically I feel that it is better to be
simple for our case.  The decision to use PUT or POST comes down to idempotency of the operation
since the HTTP 1.1 spec states that PUT is always idempotent and POST has no such guarantees.
This ties into caching and performance but at the load that would be expected for an Ambari
server, this isn't really an issue.  So I have now used a 1-1 mapping between crud operations
and http verb. This will be easier for the api developer to determine which verb to use.
> So to be explicit:
> Create = POST
> Update = PUT
