Fix RawTextParser incorrectly handling the max indentation level

Issue: #3406

Description

Fix RawTextParser internally setting a new max indentation level, independent from what the user put in.
This was done by refactoring relevant code and not using internal default values anymore.

In the help (and github pages) the parameters -h and -v get put together into one -hv which can be confusing as we also have a flag -nc which has two letters. How should this be handled?

The help for -metrics uses the internal name for the variable 'metricNames' as default value. This name was changed during refactoring. Can we manipulate the help to not use that internal value or how should this be handled?

Can be solved using a paramLabel: https://picocli.info/#_parameter_labels

This happens because picocli uses "-v" for the version flag, and it gets automatically combined with the "-h" flag. After checking the documentation, there doesn't seem to be a way to stop this, except for changing the verbose flag to something like "-ve" or a similar option.
