[libvirt] [dockerfiles PATCH] Add 'trigger' and 'monitor' scripts

[Andrea Bolognani]

These are extremely crude scripts that are nonetheless useful when
it's time to rebuild all images. Usage is along these lines:

  $ ls libvirt-debian-10* >in
  $ ./trigger in out
  $ ./monitor out 3

Error handling is almost non-existent, but realistically speaking
at most three people will ever run these scripts anyway :)

Quay has limits on both the number of jobs that can be running at
the same time and the rate of job submission: rebuilding containers
in batches, eg. all Debian 10 containers, followed by all Debian 9
containers, and so on, allows us to remain within those limits.
