Subject: [PATCH] [IDEA] Enable Gradle Configuration Cache for Gradle Test
 Runner (#123552) (#123624)

* [IDEA] Enable Gradle Configuration Cache for Gradle Runner

This should speedup repetitives usages of the Gradle Runner for the majority of test executions
We added a flag to disable it explicitly if it does not work for certain scenarios
