Add Redis interceptor tracing

See merge request gitlab-org/gitlab-ce!30238

This change adds Distributed Tracing support for two new types of events

1. Redis Calls
1. ActiveSupport (Rails) Caching Operations

The intention is to help application developers and infrastructure

the application when running at scale.

The Redis and Caching spans can be viewed in the Jaeger UI by clicking
the "Trace" link in the performance bar when running on GDK.
