Release Apache Kudu 1.7.0
release notes: some edits

- Some small wording improvements
- Moved 3-4-3 replication to new features since it seems large enough to
  not just be an "improvement"
- Added a note that the 3-disks-per-replica change only affects new
  replicas
- Stopped documenting the experimental flag which goes back to 3-2-3
  replication since we'd like to remove it in the future, and we don't
  know of any compelling reasons for someone to change it.
- Moved KUDU-2259 to "fixed issues" since it was seen as a bug
- Added a few explanations of the results of some fixes instead of the
  implementations.
