Add section to readme about avoiding extra retries in Sidekiq/Que etc

[isaacseymour]

@greysteil I think this complements #28 . The same caveats that apply to Sidekiq also apply to Que, which we already support. Does this look good to you?

[greysteil]

The cleanest approach is probably for people to disable retrying globally, but if they can't do so to use this approach - worth adding a note / clarification to that effect?

[isaacseymour]

I'm not sure, I kinda prefer doing it per-job. Doing in globally requires putting something like ActiveJob::QueueAdapters::SidekiqAdapter::JobWrapper.sidekiq_options(retry: false), which feels prety fragile, and I'm not sure it's even possible with Que (you can just set the retry delay to many seconds).

[greysteil]

Yeah, downside is that you lose any ability to manually retry failed jobs when you do it this way.

I'm :+1: on this either way - it's an improvement, and people should know their own queueing back-ends.

[isaacseymour]

Yeah, at this point it all gets super backend-specific, so mostly just want to make it really clear that it's something to be considered.

[isaacseymour]

Added another para about the alternative (Sidekiq-specific since there's no dead/failed job queue in Que, and don't know about others).
