Features

- reduced container size by ~250MB
- reorganized repo
- cleaned up Dockerfile

Features

- add a entrypoint.sh that will print lmhostid before starting lmgrd (passes all params to lmgrd)
- additional logging improvements

IMPROVEMENTS

- Eliminating all default arguments to fix both the logging issues and removing all magical paths and values. Props to @hyperknot
- Updating documentation and examples to match current behavior.

BREAKING CHANGES
- Container no longer provides auto-magical license path, use -c [license_path] instead.
- Container no longer logs to __/var/log/flexlm/lmgrd.log__, use _docker logs_ instead.

- A Docker container for running _lmgrd_.
