This version removes the default cromwell url and adds a setup process for first time users. Set up can be skipped by providing a ~/.cromshell/cromwell_server.config file or setting the `CROMWELL_URL` environment variable.
The previous default was: `https://cromwell-v36.dsde-methods.broadinstitute.org`
New features:
* submit -w flag to wait until the job has started or failed with (appropriate waiting animation)
* initial configuration so no default server is assumed
* cleanup command to remove old runs
