feat: containerize build - part 2

[ishaansehgal99]

This PR takes logic out of git action and places it into a python script and K8s jobs that can handle concurrent docker image builds.

The Python script does the following:

1. Checks the modified files
2. Creates custom docker job files for each build
3. Spawns the docker job for each build
4. Reports the success of the job back to the git action (timeout after 3600 sec)

Note: Since K8s jobs are isolated/independent, program can handle concurrent git actions running (e.g. two jobs building the same image)
