More defaults for cli args

[cornerman]

Config should be default: directory/.selery.yml

What is a good default for results?

Can we use a file instead of env args for the tokens? Is it even better than enviroment variables?

Directory is needed or just github-repo?

@cornerman you guys already have a .openselery in your $HOME so using that for a results/run-<date>/... File tree would be fine I guess, else $PWD/results/... is always an option as well.

Having defaults for the configuration is not fine however, because they should to be explicitly displayed (transparent) for CI/personal use. But most times the configuration comes with a valid project (either local or github) containing a selery.yaml so your point gets valid again. I doubt that having a specially named file is a"good" solution but ita not that bad either.

The directory argument could also be called "target" and could potentially contain a github URL. We would have to clone it locally before doing stuff with it.
