Change subject: IMPALA-6034: Add CPU and scanned bytes limits per query
......................................................................


Patch Set 11:

I was talking to Pooja offline and realised that the CPU limit implementation 
is deeply flawed because we don't update the CPU usage at any regular cadence - 
e.g. scanner threads only update it when they exit.

I'm thinking about making cpu_limit_s a "DEVELOPMENT" query option and leaving 
it undocumented until we can address that issue.

The bytes read implementation works as expected.
