Description

Every 10 seconds, we have the following INFO-level line of log:

2023-10-01 08:02:01.607 o.a.s.s.b.BlacklistScheduler timer [INFO]
 Supervisors [] are blacklisted.

I propose to change current behavior to only print the list of blocklisted supervisors only if there is at least one which is blocklisted (to use a more neutral wording than "blacklisted").
