Add new detailed documentation targeting physicist how to write easily analysis in coffea and execute it on coffea-casa AF

[oshadura]

@mat-adamec we were talking with @lgray and this task could be re-prioritized since we could use this tutorial on AGC Tools Workshop https://indico.cern.ch/event/1126109/ (cc @kenbloom )

I think I could imagine it could consist of two parts:

• [ ] 1-hour tutorial targeting physicist how to write easily analysis in coffea
• [ ] Additional tutorial targeting physicist how to execute analysis in coffea-casa (e.g. adding Servicex)

I will hope that also @nsmith- could help us with ideas what should be included in this tutorial to make it re-usable in other cases (e.g. as a part of training for example)

I suppose it needs to be experiment-agnostic? One idea that I've been meaning to put together for a while is a tag-and-probe example using the CMS open data.

@mat could you please add your coffea tutorial in coffea-casa readthedoc?

Good idea! I've added it to my to-do list.

I think you accidentally pinged the wrong Mat. Sorry to whoever that other person is. :)
