Subject: [PATCH] Add GitLab Redis initializer ordering fix

Fixes NameError: uninitialized constant Gitlab::Redis::ALL_CLASSES
caused by 7_prometheus_metrics.rb loading before 7_redis.rb
(alphabetically 'p' < 'r'). The ConfigMap provides a 0_redis_early.rb
initializer that requires gitlab/redis before other initializers run.

+# triggering Redis cache access before Gitlab::Redis::ALL_CLASSES is defined.
