This commit solves two problems: 1. Redis cache usage is tracked under `redis-rpush` because they use the same Redis URL and `redis-rpush` overrides `redis`. 2. Sidekiq jobs can enqueue an unbounded number of other Sidekiq jobs. The instrumentation cost alone of enqueuing hundreds of thousands of other Sidekiq jobs can be prohibitive, similar to DEBUG-level logging. This commit wraps it in a conditional so it must be enabled explicitly and can be turned on and off at will without a code change.
