* Add "chown" to gpg/keys in "start-local" target that so that repo-server can access gpg keys.
* * Set -u uid:gid in the docker run commands so that test images are run under the current user.
* test Procfile processes will not need to perform "su" to default user (which has the current user's uid/gid)
* Remove chown in start-e2e-local
* clean up, remove "bash -c"
* Test containers are run as uid 0 which allows uid_entrypoint.sh to perform some user setup. uid_entrypoint.sh creates a non-root user (default) and enables passwordless sudo for that user. The container entry point command is run as the non-root user. "goreman start" does "sudo" to to the processes that need root permission including sshd, fcgiwrap, and nginix. The other processes are running as the non-root user.
* use /bin/bash
* change back to sh
* Docker image to create unpriveleged testuser and enable passwordless sudo for that user
