There should be a complex example of a service based rollout and subscriber

[jejacks0n]

The general idea is to provide an example for others to use when writing their own gems if they want to. I think using Unleash for this would make the most sense, but using something like LaunchDarkly might also be useful.

Things that should be built in to the subscriber:

• Metrics on as much as possible -- variant resolution, callback times, etc.
• Include details to understand the variant resolution lifecycle.
  • Assigned manually before run?
  • Set manually in the run block?
  • Set in a run callback? (before and around)
  • Resolved through the cache?
  • Resolved through segment rules?
  • Resolved through the rollout?
  • Was the variant cached?

There's now an Unleash adapter that can be used as an example, but there was nothing to report metrics to, since Unleash has it's own metrics concept. 😅

So while the Unleash adapter is a useful example, it's not really a useful example for building out tooling for reporting.

If there are any suggestions for systems worth reporting into, I'm happy to take a request or suggestion.
