Export backend.GetMasterInfo over the rpc layer

We create a multi-node call so that querying all nodes for agreement
will be fast.

Add job queue RPC functions

jobqueue_update: Uploads a job queue file's content to a node. The
most common operation is to upload something that we already have

read again when distributing changes, but content has to be passed...

Add a rpc call for BlockDev.Close()

This patch adds rpc layer calls (in rpc.py and the equivalent in
ganeti-noded) to close a list of block devices, and the wrapper in
backend.py that takes a list of Disk objects, identifies them and

Implement block device grow at the rpc layer

This simple patch exposes the block device grow operation at the rpc
layer. It does not increase the protocol version as it has been recently
changed by the live failover rpc call.

This patch adds the migration rpc call and its implementation in the
backend. The patch does not deal with the correct activation of disks.

Because of the new RPC, the protocol version is increased.

Convert os_get to use OS rather than InvalidOS

In order to do this for simplicity we leave the OSFromDisk function as-is and
