Add RedisHLL errors into Usage Ping Redis hardening

What does this MR do?

Part of #300535 (closed) and suggested in !52334 (comment 496946395)

There are instances (e.g. in Gitlab::UsageData) of passing HLLRedisCounter to the block in Gitlab::Utils::UsageData#redis_usage_data and its errors wouldn't be rescued to return fallback value. This would potentially result in failing the entire Usage Ping generation.

This prevents that and hardens the method. All HLLRedisCounter custom exceptions are rescued, since EventError is their superclass.
