ci: Autocreate GitLab release on tag

See merge request !8

To allow viewing Changelogs easily in GitLab and associate assets (e.g.
deb packages) to a releaes, this commit creates GitLab releases for every
tag in the CI pipeline, automatically extracting the latest CHANGELOG
entry as release description.

Add deb packaging

See merge request !6

To allow automatic distribution, this commit introduces a job to publish
the packages to the FeM base deb repo.

To allow publishing of built deb packages, the artifacts need to be
signed. This commit adds a job to sign the built artifacts files to
allow uploading the deb package in a later job.

To automate the deb build process, this commit adds a CI pipeline job to
build the deb packages.

To allow distributing the plugins via our own deb repo, this commit
introduces deb packaging for the repo.

nrpe_wrapper: Modernize script

Closes #3

See merge request !5

The previous version used /bin/bash without actually using bashisms and
required check_nrpe to be in /usr/lib/nagios/plugins.

To modernize the script, this commit applies a few changes:

* Bashisms are used where possible (i.e. [[ ]] instead of [ ], $( )
  instead of ` `).
* Variables are mostly quoted (just in case...)
* The script changes to the nagios plugin dir to become independent of
  the nagios plugin installation directory. As a fallback, the
  hard-coded location for the nagios plugin directory can be used as
  well (for backwards compatibility).

Closes: #3
