More complex worker-type parameter

[toxinu]

Allow this syntax munch run worker --worker-type gc mx.

Looks like multi-value options in Click only work with fixed number of values.
That's limiting.

A better syntax might be: munch run worker --worker-type gc,mx

[toxinu]

Click handle multiple options like that: -t core -t gc [...].

I'll add a shorter parameter for --worker-type, like -t.

munch run worker --help
Usage: munch run worker [OPTIONS]

  Run background worker instance.

Options:
  -t, --worker-type [all|core|status|router|mx|gc]
        Define which kind of task worker will consume.  [default: all]

Is it ok for you?

[n11c]

Looks good.
(Obviously "-t all" needs to be mutually exclusive with others. )
