Add new SonarCloud GitHub Action and configuration; something (maybe
the way the builds were submitted) has apparently changed and the
project got deleted and the analysis wasn't working.
(cherry picked from commit 4bfbb4ddf7)
BIND 9.16 needs Python and PLY packages for configure to succeed.
Unless we want to tweak the build script to exclude python, we need to
add python3-ply package to the CodeQL configuration.
(cherry picked from commit 0622d11366)
Unfortunately, it's not possible to disable Pull Requests on the
mirrored repository on the GitHub, so this commit adds external action
that closes any new open Issue or Pull Requests instead letting them rot
unnoticed.
