Description of problem:
When restarting just foreman service, any new task invoked after the restart gets stuck in planned/pending forever.

Version-Release number of selected component (if applicable):
6.11.4
6.12

How reproducible:
100%

Steps to Reproduce:
1. Run a REX job (say execute "date command) just to see it works well.
2. satellite-maintain service restart --only=foreman.service
3. Repeat 1
4. satellite-maintain service restart --only=dynflow-sidekiq@orchestrator,dynflow-sidekiq@worker-1,dynflow-sidekiq@worker-2,dynflow-sidekiq@worker-hosts-queue-1
5. Repeat 1

Actual results:
3. gets stuck forever
5. jobs+tasks start to work again (including those invoked in 3)

Expected results:
3. tasks are completed as usual

Additional info:
Observation: Just restarting dynflow orchestrator service is not sufficient.
