pySim-shell: move command desc and verify_adm to PySimCommands

Almost all pySim-shell related commands are agrgated in PySimCommands.
There are a few exceptions, so there are some commands in PysimApp.
However, it makes sense to reserve PysimApp exclusively for very basic
commands that do not directly relate to card operations. So lets move
the command verify_adm and desc to PySimCommands.
