Enable gnt-cluster modify to hv/beparams

This patch enables the cluster modify to change:
- enabled hypervisor list
- hvparams (per hypervisor)
- beparams (only the default group)

Syntax:
gnt-cluster modify -B vcpus=3 -H xen-pvm:no_initrd_path

Validation for parameters is somewhat missing - the individual...

grow-disk: wait until resync is completed

The patch adds a new ‘--no-wait-for-sync’ parameter to grow-disk similar
to the one in instance add, and changes the default to wait.

This is cleaner as at the moment when the command returns, we either
have a fully synced disk or there is an error....

This patch adds a new '-s' parameter to ‘gnt-instance info’ that makes
