Feature Request: Add command to clear logs in container

[vnwonah]

The docker logs <container-name> command comes in handy during development to inspect console logs. After a while of running a container, it can become cumbersome to go through.

I am proposing a docker logs clear <container-name> which clears all logs in a specified container.

This command will be immediately useful to me and several other developers I believe who use custom scripts to achieve this behaviour.

You can enable log rotation on the container, as well as filter logs with "--tail", "--since", and "--until".
If you change to the "local" log driver, rotation is enabled by default.
