The CodeQL and SonarCloud GitHub Actions would FTBFS because of missing
liburcu-dev package resulting. Install the required package to both
GitHub Action files.
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.
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.
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.
