Drop Prometheus middleware from dramatiq settings

[amureki]

Prometheus client became optional in dramatiq v2:
https://github.com/Bogdanp/dramatiq/releases/tag/v2.0.0

I think we don't need to cover all our dependencies's subdependencies, so it is fine to drop it.

@codingjoe I couldn't figure this out from the first look.

Broker is now raising exceptions immediately when tasks retry.
So I wonder how should we approach this here.

Thanks, @amureki, for thinking about me and contributing this change <3

@amureki dramatic tests fail though 🙈

@amureki dramatic tests fail though 🙈

yeah, as I mentioned above, I am not sure how could we proceed here - need to evaluate this more.

I'd need to invest more time into it, but also if you have suggestions, I'd be happy to hear!
