resize-lun: Add resizePV verb
This series of patches add support resizing of a storage domain after
a LUN was resized on the storage server.
Main flow - the user initiates LUNs resize
- Engine will invoke getDeviceList verb on all the hosts, with the
specific LUNs guid. getDeviceList will rescan and resize the multipath
map if needed.
- If all the hosts are seeing the same LUN size, resizePV verb will be
invoked on the SPM, resizing the PV to the underlying device size.
Secondary flow - a host recovers from maintenance/down state
- When a host connects to the storage server, a rescan and resize of
multipath devices will be performed. This operation will make sure
that the host is synced with the storage server.
This patch adds the resizePV verb. This verb calls pvresize on a device
and returns the new PV size. This verb will extend the PV after a LUN
was resized on the storage server. This is a SPM operation.
Example outputs:
$ vdsClient -s 0 resizePV \
d24ebee6-ec30-4270-88a2-a8f38a5a804a \
5966cee6-ee28-454c-96bc-e318bed1291a \
360014057fac79f7f7dc4c15b29405f4e
size = '36104568832'
$ vdsClient -s 0 resizePV
Error using command: Wrong number of arguments provided, expecting 3

Resize PV in Storage Domain - After a block device has been
resized in storage server, this method will cause the PV to use
the entire size of the block device
