[VOTE] KIP-453: Add close() method to RocksDBConfigSetter

[Sophie Blee-Goldman]

Hi all,

I'd like to call for a vote on a minor KIP that adds a close() method to
the RocksDBConfigSetter interface of Streams.

Link:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-453%3A+Add+close%28%29+method+to+RocksDBConfigSetter

This is important for users who have created RocksOBjects in
RocksDBConfigSetter#setConfig to avoid leaking off-heap memory

Thanks!
Sophie
