Complete logs command

[vdemeester]

Add support for more flags/options for the logs command, and set the same behaviour as the compose one :

• Added --follow, --timestamp, and --tail flags to the
  docker-compose logs command.
• docker-compose logs now shows logs for new containers that are created
  after it starts.
• docker-compose logs no longer follows log output by default. It now
  matches the behaviour of docker logs and exits after the current logs
  are printed. Use -f to get the old default behaviour.

This should be fixed at some point with the related PR: #290

@vdemeester #290 and docker/engine-api#315 were both closed. Could you please comment if tail option can be supported in libcompose? Thanks.

@JayHaoDing yes at some point it will, I just have to find time to work on that again 👼
