[Log Improvement] Optimize log printing in operator logs

At present operator logs prints too much of information. This leads to a situation where important information is missed out in huge pile of lines. Kindly optimize the behaviour where some of the warnings or errors are not repeated too many times but printed enough to grab the user attention when they see the logs.

For example: When DB is down and an automated backup is initiated, message of backup not working is printed multiple times with the stack trace, which actually means the user has to dig in the logs for useful information on what broke the DB.

This is applicable for all operators.
