Change subject: IMPALA-4403: Implement SHOW RANGE PARTITIONS for Kudu tables

Patch Set 1:

Thanks, Lars!

So firstly, this functionality I think is pretty important so worth trying to get in. At first
I was thinking that plumbing this through the 'ShowStats' path was too wonky, and that we'd
probably want to just add separate classes/functions for a parallel path. However after thinking
more about it, I think it's actually not the craziest thing to consider this a kind of ShowStats
command. Right now it doesn't have any stats, but I think in the future we'd probably want
to show number of rows. There's no way to get that info today, but with some help from Kudu
it could be possible. That'd be super useful.

So to summarize, I'd be OK with this approach. We can add some TODOs about adding stats later.
Let's see what others think.
