[SPARK-22471][SQL] SQLListener consumes much memory causing OutOfMemoryError
## What changes were proposed in this pull request?
This PR addresses the issue
[SPARK-22471](https://issues.apache.org/jira/browse/SPARK-22471). The modified
version of `SQLListener` respects the setting `spark.ui.retainedStages` and
keeps the number of the tracked stages within the specified limit. The hash map
`_stageIdToStageMetrics` does not outgrow the limit, hence overall memory
consumption does not grow with time anymore.
A 2.2-compatible fix. Maybe incompatible with 2.3 due to #19681.
## How was this patch tested?
A new unit test covers this fix - see `SQLListenerMemorySuite.scala`.
