We print info logs under the debugMode flag. Whats the intention?

@heesung-sn In your PR #18964 ,you print info log in debugMode flag,
but I think when debugMode is true,we should print debug log in PR #20168

[heesung-sohn]

The intention about the info logs under this debugMode flag is to dynamically print the useful operational logs when there are issues and monitor the decision logics, without restarting brokers. One can turn off this debug mode, when done. With this dynamic flag, one may not need to change the log level as it currently outputs logs at the info level. I understand some other projects strictly matches log levels in config and code. However, it appears that Pulsar does not have such strict practice as we have other code that prints info level logs under some debug flags(e.g log.isDebugEnabled).

I would let Pulsar PMC members decide on such practice, and we follow it.

Closed as no consensus. There is no relation between debugMode and debug log level.
