Add a balloon device to all kvm instances

This can be used to resize their memory (for now only manually, as
ganeti doesn't do the job yet)

kvm: make qmp connections more robust

Currently qmp fails at connect() time if there are socket errors. (eg.
if the instance was started without qmp). Add some better checking.

Also in the only place where we use it avoid hiding the error connecting
to the socket as a failure to read the password file....

Add hypervisors ancillary files list

These lists will be used to declare some of the files not necessarily
needed on all nodes. The files selected are files without which the
various hypervisors can still work, but that when they are present
should be synchronized across the cluster (or node group)....

xen: changes to facilitate "xl" support (xen 4.1)

- Copy the xl config file, in case there's any
- Start instances by config file, not name (also xm compatible)
- Start paused domains with p and not --paused (also xm compatible)
Add a fixme for migration (changes are not xm compatible)...
