Move commandline interface to typer

[schaefi]

This commit moves the kiwi commandline and plugin interface to typer and drops the use of docopt. Typer is based on python type hints and allows for a more modern way to define Cli interfaces and auto completion, even for plugins. Also docopt is split into an old and a next generation variant and allows us to get rid of spec file hacks as well as documentation rendering hacks.

There are still open tasks before we can consider this change to go in

• stackbuild plugin needs cli.py: TBD by @schaefi
• box plugin needs cli.py: TBD by @schaefi
• is python-typer package available in all distros ?

@Conan-Kudo I'm mostly interested in getting the open questions from the checklist answered, so no need to do an in-depth review of the code changes as it's time consuming. Thanks much

We can't drop Python 3.9 support since that's required for CentOS/RHEL 9.

I found a fix to make it work on 3.9 too

@Conan-Kudo I finished the Cli change and also updated the plugins. The plugins continues to support both docopt and typer such that they can continue to work also with older versions of kiwi. The upstream kiwi should change to typer and the interface is a drop-in-replacement such that there should be no difference in the former caller semantic.

The only open question is if the typer python module is available in all distros we support. I did a short test on Virtualization:Appliances:Staging/python-kiwi and it would build the package for all targets that exists there except for ALP which is an issue that I need to resolve prior merge

Also I appreciate your feedback with regards to the other OS'es

Thanks

And there is also the question on the min version of typer in the pyproject.toml to be ok or not

• port --ca-cert option
• port --ca-target-distribution
