Admins can view and manage long running queries

**Value Proposition**

Administrators often face challenges in identifying and managing queries that take longer to execute and can impact cluster performance. Additionally it is hard to track the source of those queries and who submitted them. Currently, locating these queries and acting upon them requires correlating multiple sources including the tasks API and query logs.

**Expected outcome**

Admins should be able to list running queries and see key details about each, like how long they've been running and who started them. They should be able to easily cancel a query from this list. This will give our admin users the tools they need to maintain optimal cluster health, peak search performance and quickly identify and resolve query inefficiencies.
