As Mirek said. We have very simple pure bash completion and full 
completion in "katello shell" mode (python driven) [1].

Optcomplete seems to be nice and simple library. Every command/action in 
our cli has its own optparser instance. I guess that is the reason why 
it didn't work with the simplest settings the documentation describes. I 
briefly checked optcomplete and it seems to have support for such cases 
and it's possible to define subcommands and solve this issue [2].

On the other hand we already have the completion functionality in shell 
mode so maybe we could extract it from there, create a separate 
_katellocomplete script and use it as a bash completor for katello.
