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
SREs to understand the pressure that caching operations can have on
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.

Resolve "Mirroring for external CI/CD repositories should not store OAuth token"

See merge request gitlab-org/gitlab-ce!31488

Tokens do not have this problem.

This change removes the OAuth2 option from
the import page for CI/CD only, and only
provides the personal access token form.
