rest: support DELETE HTTP request method

Reuse endpoints in order to add deletion operation such as "/server".
This way there is no need to declare a different if/else block in order
to parse a new URI for the new "*/delete" endpoint.

Current deletion operations are implemented using a different endpoint
name such as "/client/delete", "/center/delete" with POST request method.

Endpoints using "/delete" suffix may not be removed for backwards
compatibility. Adding HTTP method DELETE support for endpoints such as
"/center" or "/client" can use the already existing *_post_delete*
functions.
