[jira] [Work logged] (BEAM-8166) Support Graceful shutdown of
worker harness.
[ https://issues.apache.org/jira/browse/BEAM-8166?focusedWorklogId=308128&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-308128 ]

Work Description: lostluck commented on pull request #9504: [BEAM-8166] Allow in process workers to exit without killing the process.
URL: https://github.com/apache/beam/pull/9504
Allow for runners that do not spawn distinct processes for workers. InProcess runners can be useful for testing, or to support for any future native go runner. When running multiple pipelines simultaneously, it's desireable to allow for some measure of independance as well.
Responding fatally on GRPC connection terminations prevents these behaviours.
Further, improve the error messages to include additional context when there are GRPC issues.

> Ideally there should be a clear Shutdown control RPC a runner can send a worker harness to trigger an orderly shutdown.
> Absent that, errors on the runner side shouldn't manifest as SDK worker harness errors. SDKs should log, and gracefully shutdown from GRPC errors.
