partitioning and formatting functionality.

Request:
	POST /image/create/basic
	{
	   "clients":[
	      "192.168.56.11"
	   ],
	   "disk":"1",
	   "partition":"1",
	   "code":"131",
	   "id":"8",
	   "name":"debianbasica",
	   "repository":"192.168.56.10",
	   "sync_params":{
	      "sync":"1",
	      "diff":"0",
	      "remove":"1",
	      "compress":"0",
	      "cleanup":"0",
	      "cache":"0",
