"htcanalyze --help" needs a description line

[TobiasKadelka]

Hey,

for most command line tools, when calling the --help, they also include a short line that describes what the tool does, for example:
❱ cat --help
Usage: cat [OPTION]... [FILE]...
Concatenate FILE(s) to standard output.

I would like to see something like this for htcanalyze, too :)

I see it's not hard to do it, but I now recognised, that the use of configargpasre is completely useless.
Configargparse parses the description like this (which is ugly):

Analyze and summarize HTCondor-Joblogs Args that start with '--' (eg. -f) can
also be set in a config file (/etc/htcanalyze.conf or
~/.config/htcanalyze/htcanalyze.conf or

Because of too many Issues that are related to this tool, have a look into #90, I would again change back to something like configparser, as this is much more comparable with this facility.

In order to fix this Issue we have to address #90 first.
