KAFKA-4488: UnsupportedOperationException during initialization of
StandbyTask
Instead of throwing `UnsupportedOperationException` from
`StandbyTask.recordCollector()` return a No-op implementation of
`RecordCollector`.
Refactored `RecordCollector` to have an interface and impl.

> Fix For: 0.10.1.1
>
>
> When initializing StandbyTasks an `UnsupportedOperationException` is thrown
> from `StandbyContext.recordCollector()`.
> This occurs when `StateStore.init()` is called and logging is enabled. In
> these cases, we attempt to create a `StoreChangeLogger` that in-turn attempts
> to get the `RecordCollector`
