Add Refresh command

This patch allows us to execute refresh command using ogClient. This command
gets all the configuration in our machine and send this information to the
server. The format of the message that ogClient will send to the server will be:

{"disk": "1", "partition_setup": [{"partition": "1", "code": "LINUX",
"filesystem": "NTFS", "size": "498688", "format": "0"}, {"partition": "2",
"code": "LINUX", "filesystem": "NTFS", "size": "498688", "format": "0"},
{"partition": "3", "code": "LINUX", "filesystem": "NTFS", "size": "498688",
"format": "0"}]}
