[VOTE] KIP-264: Add a consumer metric to record raw fetch size

[Vahid S Hashemian]

In the absence of additional feedback on this KIP I'd like to start a 
vote.

To summarize, the KIP simply proposes to add a consumer metric to track 
the size of raw (uncompressed) fetched messages.
The KIP can be found here:

Thanks.
