Description - Adding local mode to the existing cluster endpoint so that it can be easier to find out which queries are running on the local coordinator instead of the whole cluster when running disaggregated coordinator mode. Figuring out local information can help with debugging purposes.
Test plan - Created a unit test that runs and queues multiple queries on different coordinators. The test checks that if local mode is enabled when requesting statistics from a cluster, the amount of queries that are running locally on that specific coordinator are returned instead of the amount of queries running on the whole cluster.
