Add --hostname argument and DBX_CONTAINER_HOSTNAME env var

[sandorex]

I thought it would require more changes but its already passed to podman so why not have it as an option when it requires so little work

[sandorex]

This would also remove the need for --init-hooks 'echo "$(uname -n)" > /etc/hostname' hacks which while they do kinda work they dont set the env var HOSTNAME and require more hacks on top of it

That's a good idea @sandorex thanks!

Can you also adjust the documentation in docs/usage and the entry in useful_tips?
Thanks!

Sure ill look into it now

I have not updated the shell autocompletions cause frankly it looks like magic 😄

[89luca89]

Autocompletion works with the --help so that should already be sorted :)
