Is your feature request related to a problem? Please describe.
Executing with k9s into containers that have no shell is impossible

Describe the solution you'd like
to add ether a way to overwrite the default <s> behavior or add a (super shell) so <ctrl-s> behavior so it uses cdebug to exec into a container

Describe alternatives you've considered
not familiar with any, except for running cdebug locally and executing into the pod

Additional context
this may be a plugin topic but i am unfamiliar with how much can they add/change/modify
