Thanks! I'm going to merge this one since the concern from @koeninger is 
addressed.

No, if we backport this I would plan to continue to backport changes (that 
are safe) until the next release.  Either way this should not affect what goes 
into master.

Does backporting reduce the likelihood of change if user feedback indicates 
we got it wrong?

My technical concerns were largely addressed, that's my big remaining 
organizational concern.

@marmbrus @zsxwing I agree its experimental and we should have more 
flexibility here with backports. I also very much agree that structured 
streaming in its current state on 2.0 isn't usable - but I'm not super sure 
that backporting fixes is the best way to do this? Honestly I spend most of my 
time focused on Python & ML (and I've only really been looking at structured 
streaming with those two hats on).

I'm really cautious about the idea 2k+ line backport which hasn't even been 
released otherwise but I don't have any specific objections to the changes its 
just making me nervous. The fact the whats being backported seems to still be 
under development is also concerning since doing this backport now puts us in a 
position of backporting more (not yet merged into mainline) fixes.

Of course - If the people with the most experience in this area all agree 
(and most of y'all [ @marmbrus @zsxwing @tdas but maybe missing @koeninger  ] 
seem to already be on this PR so I'll leave you to it) that this backport 
reasonable that is great - it would probably be good to follow up to the 
original backport mailing list thread and update the wiki as well.

We should definitly vet this PR carefully to make sure its safe.  One thing 
that is missing from that guide, that I do believe is accepted practice, is 
more leeway when the feature is marked experimental (i.e. during Spark 1.0-1.3 
I used to backport pretty much everything that went into SQL).  Since I think 
many people are simply not using structured streaming due to lack of kafka 
support, I'd error on the side of more users sooner.  If you think any part of 
this PR is unsafe with respect stable components though, please do raise those 
concerns.

@holdenk this is basically adding an external project. Without the Kafka 
source, it's hard for people to test Structured Streaming with their real data. 
Considering 2.0.2 will be out before 2.1.0, it's better to add this one into 
branch 2.0 in order to test it early. Since Structured Streaming is 
experimental, it won't break any production usage and should be safe.

This is rather a lot of functionality to backport, our backport guide 
doesn't seem to quite line up with this (based on  
https://www.mail-archive.com/dev@spark.apache.org/msg10284.html / 
https://cwiki.apache.org/confluence/display/SPARK/Committers#Committers-PolicyonBackportingBugFixes
 ) but @pwendell will know better.
