Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.
This effectively changes src/access/org.libvirt.api.policy entries:
org.libvirt.api.nwfilter.binding-create ==>
org.libvirt.api.nwfilter-binding.create
org.libvirt.api.nwfilter.binding-delete ==>
org.libvirt.api.nwfilter-binding.delete

It was found that in cases with host devices virProcessKillPainfully
might be able to send signal zero to the target PID for quite a while
with the process already being gone from /proc/<PID>.
That is due to cleanup and reset of devices which might include a
secondary bus reset that on top of the actions taken has a 1s delay
to let the bus settle. Due to that guests with plenty of Host devices
could easily exceed the default timeouts.
To solve that, this adds an extra delay of 2s per hostdev that is associated
to a VM.
