What does this PR do?

This PR is for creating a config.yaml file and moving certain smp ci parameters into the experiment.yaml file. These are changes that will be part of the next SMP release that will release a much improved version of local run. New and future experiments will need to follow the new format that is documented more closely here

Motivation

In order to improve the user experience for SMP and specifically SMP local run we have moved multiple CI flags into .yaml files instead of being command line prompts. This should help users more easily use local run.

Additional Notes

This will need to be merged in after the next SMP release officially comes out
