Kick off scheduled job in GHA

[zsusswein]

I'm not totally sure how to prioritize this issue, but I want to note the steps I think it'll take to implement kicking off a job via Github Actions.

We'll need to:

1. Add the image that runs the deployment code to a container registry
2. Add a workflow that:
   1. Instantiates a deployment container
   2. Generates configs
   3. Calls the appropriate model image, pool, and job
   4. Runs the script to assign the tasks to the job

I don't think this should be too challenging because we have a working script locally and the script takes all necessary parameters as arguments or a default env var configuration for Azure creds.

We'd want this job to run off of main on both a schedule and via workflow dispatch for on-demand runs. It should take arguments to pass through to the config generator.
