For example, if someone runs

GITHUB_REPOSITORY=douglasnaphas/madliberation GITHUB_REF=refs/heads/master @cdk-turnkey/stackname --suffix xyz --region us-east-1

they should get

DouglasnaphasMadliberationMaster-xyz-ue1

If someone wanted this, they could just manually incorporate their region into their suffix.
