Implemented both the dry run and local flags.

Added test cases to show that both flags are operating as intended.
Removed the print statement "running in local mode" as in PR#35112

The previous attempt at the PR (PR#35050) was reverted for causeing a flake.
I believe that setting the deployments terminationGracePeriodSeconds to 0 should
take care of it. I ran hack/make-rules/test-cmd.sh 50 times in a row without encountering
the flake
