executor-queue: Update frontend proxy to point to new executor-queue
Created by: efritz
Update the enterprise frontend proxy that handles requests to the precise-code-intel-indexer to point to the new executor-queue service. This closes https://github.com/sourcegraph/sourcegraph/issues/14885.
This change must correspond with a deployment of the executor-queue service in production environments. This change should also correspond to a deployment of the new executor on GCP nodes. A non-symmetric deploy will cause the executor to 404 on all routes when polling for work (causing a short period where the queue will grow without being processed).
