Parameterised config file location

[d3anp]

I'd love for the config.yml file to be a configurable item that is passed as a parameter to main.py.

This would enable building the playbooks to multiple environments (dev and prod), as well as additional flexibility when using atc-react as part of a CI/CD pipeline.

Hi @d3anp! Thank you for your proposal, once again (: Would you like to implement that feature yourself?
