[ariaieboy]

In V4 telescope introduces a new job that uses the queue system to fix the pending jobs problem #1349

This job uses the default queue of your application.

Sometimes this JOB can make thousands of pending jobs in your queue. and block your important jobs.

With this PR we can change the telescope queue and connection to something else and manage this jobs in a separate queue.

There are multiple request about this feature before here:
#1459
#1392
#1393
#1377
