Make work with Sidekiq 5

[krisleech]

We need to stop using sidekiq's #delay method as this no longer works in Sidekiq 5, see: https://github.com/mperham/sidekiq/wiki/Delayed-extensions

Related to #7

I think you mean sidekiq 5.x, Rails 5 and sidekiq 4.x work fine 😄

[rromanchuk]

btw, if anyone is reading this and needs to use 5.0 you can hack it back in with Sidekiq::Extensions.enable_delay! in your initializer until this is decoupled

[krisleech]

@rromanchuk Indeed that is what I meant, fixed. Thanks.

If anyone fancies taking a stab at this please do, it should not be too tricky, I just don't have time right now.
It might even be best to copy/paste the #delay code from sidekiq < 5 in to the broadcaster so it works exactly the same as it always has.

[krisleech]

I have started work on this in branch sidekiq5-compatibility. It can be used with any version of sidekiq. If using Sidekiq 5 then Sidekiq::Extensions.enable_delay! is no longer needed.

Please report back any success/failures.

This change will also allow full control over how we interact with Sidekiq, allowing, for example, the queue to be specified, in a future PR.

fixed in master
