This adds most of the end-to-end tests described in the test plan.
See http://goo.gl/v3Strz.
* End-to-end test for disk spill encryption.
* Admission control test for the case when acquiring initial
reservation fails.
* Initial reservation acquire failure test
* scratch_limit tests for Join, Agg, Sort, Analytic
* Memory usage scaling tests for Join, Agg, Sort, Analytic
Also splits out the slow sort queries in test_spilling and moves them
to exhaustive so the individual tests run faster and have better
parallelism.
Testing:
Ran all the core tests. Will do a full exhaustive run before
committing.
