Régis Behmo d9486018a2 feat: add --mount option to local/dev
The `--mount` option is available both with `tutor local`
and `tutor dev` commands. It allows users to easily bind-mount containers from
the host to containers. Yes, I know, we already provide that possibility with
the `bindmount` command and the `--volume=/path/` option. But these suffer from
the following drawbacks:

- They are difficult to understand.
- The "bindmount" command name does not make much sense.
- It's not convenient to mount an arbitrary folder from the host to multiple
  containers, such as the many lms/cms containers (web apps, celery workers and
  job runners).

To address this situation, we now recommend to make use of --mount:

1. `--mount=service1[,service2,...]:/host/path:/container/path`: manually mount
   `/host/path` to `/container/path` in container "service1" (and "service2").
2. `--mount=/host/path`: use the new v1 plugin API to discover plugins that
   will detect this option and select the right containers in which to bind-mount
   volumes. This is really nifty...
