Consumer.commit method instead of record.offset.commit

[svroonland]

Enforces that a Consumer is in scope when committing an offset, instead of record.offset.commit.

Also:

• Remove deprecated merge method from OffsetBatch
• Combine OffsetBatch.add and OffsetBatch.commit

See also #1022, #1042.

I like where this is going... :)

Cool. This would be a backwards-incompatible change, so it has to be worth the benefits. We could perhaps deprecate the old commit method for a while.

Yes, definitely.
