[Feature Request] Support cluster write block in pull-based ingestion #18279
Description
Is your feature request related to a problem? Please describe
Support cluster write block in pull-based ingestion. This will help pause the poller when a write block is active preventing issues like disk-full among others.
Describe the solution you'd like
Enhance the stream poller to listen to cluster state changes and pause poller when a write block is active. Resume if write block is removed. Thanks for @msfroh for the valuable suggestions regarding this solution.
