[BUG] Sweeper period setting has no effect

[spapadop]

What is the bug?
Setting plugins.scheduled_jobs.sweeper.period to a different value than the default, for example 60m does not have any effect, as the sweeper keeps on running every 5 minutes, which is the default value.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Set plugins.scheduled_jobs.sweeper.period to 60m on opensearch.yml
2. Restart the cluster nodes
3. Observe that these logs will keep on appearing every 5 minutes

   [INFO ][o.o.j.s.JobSweeper       ] [node] Running full sweep
   

What is the expected behavior?
If plugins.scheduled_jobs.sweeper.period is set, the cluster should respect it and run sweeper accordingly.

What is your host/environment?

• OpenSearch v2.11.0 with all default plugins
