1.0.0 Branch Update

[Guozhang Wang <wa...@gmail.com>]

Hello Kafka developers,

This is another update on the 1.0.0 release progress.

We were planing to close the code freeze and make the first RC by today,
but we are behind our schedule a bit. After making a pass over all the
JIRAs to move non-blockers to the next release we still have 20 tickets
ongoing, and three KIPs not yet being merged (namely, KIP-91, KIP-180,
KIP-196). Among these tickets, 5 are marked as blockers for now.

I have also created the release branch for 1.0.0 and trunk has been bumped
to 1.1.0-SNAPSHOT. From this point, most changes should go to trunk except
the above mentioned JIRAs which needs to be double committed. Newly created
tickets should only be marked as 1.0.0 issues if they are critical bugs.

* For contributors working on existing or new issues, please discuss with
your reviewer whether it is really a 1.0.0 blocker, and if your PR could be
merged soon and make it to trunk+release. Our goal is to have zero JIRAs by
the end of this week in order to make the first RC.


Thanks!
