#915 Add POST "image/setup" command to REST API in ogAdmServer

This patch implements the command "image/setup" that provides partitioning and
formatting functionality.

Request:
	POST /image/setup
	{ "clients" : [ "192.168.56.11" ], "disk" : "1", "cache" : "1", "cache_size" : "0",
	"partition_setup":
	[{"partition": "1", "code": "LINUX", "filesystem": "EMPTY", "size": "498688", "format": "0"},
	 {"partition": "2", "code": "LINUX-SWAP", "filesystem": "EMPTY", "size": "199987", "format": "0"},
	 {"partition": "3", "code": "LINUX", "filesystem": "EMPTY", "size": "31053824", "format": "0"},
	 {"partition": "4", "code": "EMPTY", "filesystem": "EMPTY", "size": "0", "format": "0"}]}
