Add 'restore image' command

Adds cli capability to send image restore commands to the ogServer.

It has the following options:

	--id
	To specify image id

	--disk
	Target disk

	--part
	Target partition

	--type
	To specify type of restore to send. UNICAST-DIRECT or
	UNICAST-CACHE are supported as of this patch.

	--repo
	Optional argument to specify image repo to fetch the image. This
	applies for UNICAST-DIRECT cases. (not restoring from a cache
	partition). If not specified it will default to rest.URL ip
	(ie. ogServer ip)

	--client-ip, --room-id and --center-id
	Target client args
