deadlock was happening as: * `markCacheSynced` holds `datasourceToSegmentCache` lock; waits `HeapMemoryDatasourceSegmentCache` for an empty one * `writeCacheForDataSource` acquires `HeapMemoryDatasourceSegmentCache` lock and tries to `HeapMemorySegmentMetadataCache#getCacheWithReference` which needs the `datasourceToSegmentCache` lock tests like `KafkaClusterMetricsTest` may start hanging due to this see stacktrace and repro [here](https://github.com/apache/druid/commit/0656c91f56b905d21a84f0bcd13194ea94bbbf75#diff-a78f4b6325af1f9555e1c62fb2d0a06020dcad2c6c821aea3f9460b646a32862) -- This is an automated message from the Apache Git Service.
