Added a toggle button that steers queries to overlord or sql. We will default it to overlord to reduce metadata stress. Fixes #12318 This PR fixes the first part of the solution recommended using UI (https://github.com/apache/druid/issues/12318) ### Description As tasks increases, UI start putting a lot of stress on metadata store as its required to fetch the whole table to parse the status of the task for filtering and displaying in the UI. We have seen an upward of 3x network throughput on our metadata store and resulting in degraded performance. This PR fixes this issue in the UI by introducing a toggle switch that defaults to overlord for fetching task listing and thus avoiding such stress on metadata store.
