Quiet flag for the task drop?

[lorenzosinisi]

I have noticed that the flag 'quiet' is not available for the task that drops the db. Shall we add it? I could open a PR for that in case.

We can do here https://github.com/commanded/eventstore/blob/master/lib/mix/tasks/event_store.drop.ex#L23 something like this https://github.com/commanded/eventstore/blob/master/lib/mix/tasks/event_store.init.ex#L27

Yes, happy to accept a PR if you want to add this flag to the task.
