Add instance for profiler commands

[tuman-area]

Now commands logic splitted between cli.py and profiler/controller.py. With this implementation it's hard to add and handle new commands.

Hi @axelbunt54,
Could you tell me what the ask is here?

Hi @dpereowei,
Thanks for looking at this😅 I was not expecting someone to really come and contribute haha!

Actually, I'm not quite sure about the best implementation here: now I have a list of string commands in cli.py and a process_command function in controller.py that also takes strings. It feels like a bad solution. I thought about creating some new module with a class for every command (containing name, help text, attributes, etc.), but didn't come up with something concrete...
What do you think?

Hi @axelbunt54,
You're right to think about refactoring, I think defining command classes with a shared base interface would be a good way to go
