[FLINK-8860][flip6] stop SlotManager spamming logs for every TM heartbeat
at log level 'info'
## What is the purpose of the change
For every `TaskManager` heartbeat message, `SlotManager` was writing the
message `Received slot report from instance...` into the logs at info level
although this is clearly a debug information that is even already printed with
a different of detail by the `ResourceManager`.
## Brief change log
- change log level of a slot report to `debug`
