#915: Add POST /image/create command to REST API in ogAdmServer

This patch implements the command "image/create" that creates an image
in a client.

    Request:
            POST /image/create
	    { "clients" : [ "192.168.2.1" ], "disk" : "1", "partition" : "1", "code" : "1", "id" : "1", "name" : "test", "repository" : "192.168.2.2" }
