Various improvements

Most importantly, I rewrote the CMK plugin to improve the readability of the service summary and introduce a prase function.

any plans on making this work on 2.3?

I just checked and it works with 2.3, however when updating the checkmk server, it seems to reinstall the package from last known mkp. The fix for me was just to repackage it (mkp release fail2ban, then mkp template fail2ban, and mkp package fail2ban.manifest.temp). From the doc: https://docs.checkmk.com/latest/en/mkps.html#release_mkp

I edited the manifest and put version 1.9.2 in there and was able to successfully make the new mkp work. It should survive the next checkmk update. Here is my manifest for anyone interested in quickly repackaging it:

{'author': 'JensKuehnel',
 'description': 'Monitor fail2ban jails',
 'download_url': 'https://github.com/FreifunkBremen/fail2ban-check-mk/tree/master',
 'files': {'agent_based': ['fail2ban_checks.py'],
           'agents': ['plugins/fail2ban'],
           'checkman': ['fail2ban'],
           'lib': ['check_mk/base/cee/plugins/bakery/fail2ban.py',
                   'python3/cmk/base/cee/plugins/bakery/fail2ban.py'],
           'web': ['plugins/metrics/fail2ban_metric.py',
                   'plugins/wato/fail2ban_parameters.py']},
 'name': 'fail2ban',
 'title': 'fail2ban',
 'version': '1.9.2',
 'version.min_required': '2.3.0p6',
 'version.packaged': 'cmk-mkp-tool 0.2.0',
 'version.usable_until': None}

After that, if you check with mkp list, you will see you are using that new 1.9.2 version. You can disable and remove 1.9.1.
