O-Subject: [RHEL8.2 hyperv-daemons PATCH] Set IgnoreOnIsolate=1 in systemd units

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1769920
Branch: rhel-8.2.0
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=24699501
Upstream: RHEL-only (upstream doesn't ship systemd units)

Hyper-V daemons' units are udev activated: when the appropriate device
appears systemd unit is started and normal targets (e.g. multi-user.target)
don't depend on these units. With systemd it is possible to try to isolate
the target (somewhat similar to switching runlevel), this is supposed to
shut everything which the target doesn't depend on (like units started
manually) off. It seems that the general users' expectation is that
hyperv-daemons units survive the procedure.
