Cleanup

[georgevreilly]

Summary

Much cleanup

Impact

Breaks internal uses of FlyingCloud

Limitations / TODO

Detail

• flyingcloud command is now a Bash wrapper around the Python main
• flyingcloud command supports --build (default), --run, and --kill operations.
• flyingcloud.yaml has separate registry stanza
• layer.yaml now has:
  • help and description fields
  • richer port mapping, host_port: container_ports(s)
• Much cleanup of DockerBuildLayer:
  • replaced class-level attributes with instance attributes; simplified
  • do_run operation's default implementation runs an FC layer's
    in a Docker container with correct port mapping;
    also tunnels ports via docker-machine ssh, if needed.
  • do_kill operation cleans up Docker container, shuts down SSH port forwarding.
• Improved main.py's YAML parsing
• Moar tests!
• python setup.py test runs the FlyingCloud tests
