This adds `events` subcommand for objects that emit events. The following
subcommands have been added:

- `docker builder events`
- `docker container events`
- `docker image events`
- `docker network events`
- `docker plugin events`
- `docker volume events`

And if swarm-mode is enabled:

- `docker config events`
- `docker node events`
- `docker secret events`
- `docker service events`

For example:

    docker container events --help

    Usage:  docker container events [OPTIONS]

    Get real time container events from the server

    Options:
    -f, --filter filter   Filter output based on conditions provided
    --format string   Format the output using the given Go template
    --since string    Show all events created since timestamp
    --until string    Stream events until this timestamp

Which allows for an easier way to get (e.g.) container events:

    docker container events

Which is the equivalent of:

    docker events --filter type=container
