Clean up and make cluster Make targets consistent. (#359)

Change Makefile targets for running the Yunikorn services to make
testing a separate UHS instance a bit easier. Developers can now use
`make create-cluster` and `make delete-cluster`, to be consistent with
Kind's `create-cluster` and `delete-cluster` commands.

Fixes #356
