sync: bound the janitor and telemetry steps (docker exec hangs in an IO stall)

09-23 16:43Z the Veron data2 SMR stall left runc exec in D state; the
janitor's docker exec never returned, so the sync sat 'activating' and no
repo mirrored or got a status for any lane. Both steps are non-fatal;
now they time out (120 s / 180 s) and the run continues.
