Fail the health check as soon as a resource becomes stalled
without waiting for the timeout to expire.
This behavior can be disabled using the `DisableFailFastBehavior` feature flag.

This commit allows the disabling of the caching cluster reader used by
the status poller while waiting and/or checking the health of resources.
Potentially reducing the memory usage of the controller on large scale
clusters, at the cost of an increase in direct API calls.
The feature can be enabled using
`--feature-gates=DisableStatusPollerCache=true`.

You can re-enable caching by starting the controller with the argument
`--feature-gates=CacheSecretsAndConfigMaps=true`.
