Lower the frequency of which job trace updates occur [RUN ALL RSPEC] [RUN AS-IF-FOSS]

What does this MR do?

Related to #324371 (closed)

When a job trace is not being watched by a user we tell the runner to send traces less frequently. If instead it's being watched we tell the runner to send traces more frequently.

To reduce further the requests when the trace is not being watched we can increase the interval from 30s to 60s.
