[Revalidation] Add script to initialize the revalidation job (#531)

This script will be run on the first deployment of the revalidation job. It calls the initialization phase and exits. This script can be registered as a Windows service as:

1. The initialization phase verifies that the initialization phase hasn't previously completed. If it has previously completed, the initialization phase exits.
2. The initialization phase cleans up the state if the previous initialization attempt failed.
