While making snapwatchd, the binaries are also installed. If DESTDIR is
not set, it means that the binaries will be installed to the /
directory. Create a temporary directory, and set that as DESTDIR to
avoid polluting the root directory.

CA-135649: Add additional HBA information to sr-probe and sr-create

There currently is no easy way to gather the basic information about HBAs, that
are required for provisioning external storage.

This commit adds some basic information about the FC and iSCSI HBAs to the
HBA-specific output of "xe sr-probe type=LVMoHBA" and "xe sr-create
type=LVMoHBA" to address this gap.

CA-136790: Enable online expansion of LVHDxSRs

Attempt to expand the size of LVHDxSRs by growing into additional available
space, if extra space exists on the backing device during sr-attach of the
master or sr-scan.

If the master detects that the LUN has been resized, it will synchronize
with the slaves. If all nodes succeed to refresh the size of the LUN, the
master will go ahead and resize the PV.

This commit supersedes the limited undocumented functionality to expand
LVHDxSRs that we had before. The master used to do the resize after a reboot
during sr-attach. Pool members needed to be rebooted after the master as there
was no synchronization between pool nodes.
