Configuration setting for the FF_RETRIEVE_POD_WARNING_EVENTS flag

Description

This request is on behalf of a customer.

Support ticket - internal only

Proposal

Requesting to keep the FF_RETRIEVE_POD_WARNING_EVENTS feature flag. When using a new on-demand instance (for example AWS Spot instance), enabling this flag causes a lot of warnings regarding node availability until the instance is available which is not a real issue. With the removal of this feature flag in 18.0 there will be no ability to turn off logging these warnings.
