Auto provisioning of PW clusters from GitHub CI added (#3051)

# Description

This update to the GitHub dispatched CI pipeline to execute the
self-hosted GitHub Runner on Parallel Works now adds the feature that
starts up the virtual compute cluster automatically. We now have a
complete end-to-end automated process for running CI tests in Parallel
Works.

Next steps would be tear-down and adding more test to see if it scales.

It also has the update for getting a PR to load up when its originating
from a forked repo.

# How has this been tested?

The start up aspected has been tested from my forked repo but could not
test repos that are forked.
The test from forked repos has to be tested once the workflow pipeline
in the **develop** branch.
