Add `pycli` recipe to testenv
I saw someone using ncs_pycli last week at the NSO DevDays. I was not aware of it, but it seems like an obvious choice to include in the skeletons.
Starts IPython in the dev container, attach it to the NSO container
network namespace and then use ncs_pycli
to set up the MAAGIC root
and a MAAPI transaction.
