skip collection of attempts when maxAttempts is Infinity

[Tithra]

Potential issue in a scenario of retryCount = -1

In the scenario that an app instance can acquire to the lock while other instances wait for the lock, the attempts array will keep collecting stats as long as the routine() is still on hold. E.g. the app instance subscribes to external service for a regular polling may want to hold the lock forever until an error occurs or the app instance is down. That would eventually be a memory-leak issue in other app instances who wait for the lock, because each retry failed to obtain the lock => attempts array will collect 1 stats.

So in this scenario, there should be either a maximum limit for attempts to collect the stats, or may just skip the collection.
