CTS2F2 — Create/Update in WADL use the wrong HTTP methods

In the WADL (REST PSM), a Create is done with an HTTP 'PUT' and an update is done with an HTTP 'POST'. This is problematic because a client must have knowledge of the URL structure before doing a create. It will limit implementation as-is because clients cannot be expected to know the URL structure of a resource before it is created. In the case of an update, a 'PUT' is more appropriate because we assume that at that point the client does know the URL of the resource.

Change all creates to an HTTP 'POST' and all updates to an HTTP 'PUT'.
