Bash completion

[ppalaga]

It looks like we could leverage https://github.com/juven/maven-bash-completion/blob/master/bash_completion.bash

We could either copy and adapt or contribute there.

We'd need to add our own commands like --stop, --status, etc. (I am not sure we should also add all -Dmvnd* props that can be passed on the command line.)

Once we have an adapted script somewhere, we need to figure out, how to activate it using sdkman and Homebrew.

The merged fix introduces a new mvnd option called --completion that accepts a shell name. bash is the only shell supported at this time.

If you are on Linux, you can activate the completion permanently as follows:

echo 'source <(mvnd --completion bash)' >> ~/.bashrc
