There are instances (e.g. in Gitlab::UsageData) of passing
HLLRedisCounter to the block in #redis_usage_data and it's 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.
