livemigrate : activate xbzrle cache
...
This help migrate for vm with of lot of memory access (like database)
live migration tests working:
kvm 1.2 -> kvm 1.2 (xbzrle set on both side)
kvm 1.1 -> kvm 1.2 (xbzrle on target)
kvm 1.1 -> kvm 1.1 (xbzrle not set, qmp command try to set xbzrle but fail)
failing migration
kvm 1.2 -> kvm 1.1 fail, but this is expected.
I tested with a memory benchmark running on the vm with 4GB ram
without xbzrle : migration take 10min, with many network hang
with xbzrle : migration take 1min, no hang
I display xbzrle counters for debug purpose, we can remove them later

migrate: syncdisk : avoid scanning shared storage
...
Currently we get list from PVE::Storage (for unused volumes), from all storage.
If something goes wrong with the network on host and thenwe can't communicate with a network shared storage(sheepdog,rbd,..),
the vdisk_list die (timeout) and we cannot migrate the vm on another kvm host.(online or offline).
We don't need to scan shared storage, as they are no disk to sync.
