We shouldn't change this method. Please add a new method which waits on the new metric.

This property is already added to EmbeddedBroker. Do we need to add it here too?

Please put each arg in a separate line.

Nit: Lambda can be simplified

Please put the entire new logic in a separate method.

This should be put in the new method as well.

Don't return anything. Perform the metric emission here itself.

As follow-up of #18497 , this PR re-enables the embedded tests in
CentralizedSchemaMetadataQueryDisabledTestWeirdly, this is not unblocking
CentralizedSchemaPublishFailureTest(the no. of segments skipped and the no. of segments refreshed seems to be changing erratically in tests and is never what we want, will take a look at those tests in separate PR.)
