Warning log to verbose in RemovedPartitionState

[bmaggi]

Hi,

In case of lot of topics and/or partitions this log is becoming huge

log.warn("Dropping polled record batch for partition no longer assigned. WC: {}", recordsAndEpoch);

add will be truncated by some log tooling (for Example in Datadog)

I think that the useful information at warn level are the topic name and partition number.

The full state of EpochAndRecordsMap may be logged at the debug level

Regards
Benoit
