Launch docker:up with tunnel from jetpack cli

#### Is your feature request related to a problem? Please describe.

I'm a lazy Jetpack developer. I don't want to mess around with multiple terminals.

#### Describe the solution you'd like

`jetpack site [args]`

Launches a site in a new docker container.

Some possible args:
`--name=mysite` (a name used to refer to this site - you should be able to launch multiple sites on the same machine without conflicts, in individual shells)
`--modules=photon,likes`
`--plugins=woocommerce,wcship`
`--subdomain=goldsounds6`
`--tunnel=true/false`
`--tail` (tails the logs in the same shell, including debug.log)
`--` (everything after this is passed through to `wp site create`?)

Output:

```
Launching Jetpack with photon & likes
Jetpack launched on localhost:67263
Tunnel available at http://goldsounds6.jurassic.tube
```

#### Describe alternatives you've considered

Doing everything manually. Which is a hassle.

Start by locating the Jetpack CLI entry point and the existing docker:up workflow, then review how arguments could be passed to wp site create. Done would include a jetpack site command supporting the requested site, module, plugin, subdomain, tunnel, tail, and pass-through options without conflicts between simultaneous sites.
