CP-8629: Direct PPA install

A build system behind a firewall cannot use apt-add-repository directly.

CP-8629: Install to temporary directory

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.
