Cherrypick #1194 to master - Fix deploy.sh moving the unpacked repo

[ankushagarwal]

• Fix deploy.sh moving the unpacked repo.

• It looks like GitHub is stripping out the v in the name of the top level
  directory.

Make the scripts less brittle by not assuming the top level directory
will be named a certain way.
Related to #1193.

• Fix indent.

• • Add simple test scripts to verify that the configs are created

• Add an option to gke/deploy.sh to skip deployment to facilitate testing

• Add an option to gke/deploy.sh to not recreate the DM configs if they
  already exist; the sed commands assume we are starting from scratch.

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored or co-authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this state. It's up to you to confirm consent of the commit author(s) and merge this pull request when appropriate.
