Re-create instance disk symlinks on activate
This patch implements recreation of instance disk symlinks when theactivate-disks operation is run. Until now, it was not possible tore-create these symlinks without stopping and starting or migrating aninstance as the RPC call where this is done was in instance startup...

cluster verify: add hvparams verification
Currently, the validity of the hypervisor parameters is only checkedat init/modification time, and not in the cluster verify. This is bad,as it can lead to inconsistent state that is only detected when thenext modification (which can be unrelated) is made, leading to...
