Casey Ching f288867833 Stress test: Various changes
The major changes are:

1) Collect backtrace and fatal log on crash.
2) Poll memory usage. The data is only displayed at this time.
3) Support kerberos.
4) Add random queries.
5) Generate random and TPC-H nested data on a remote cluster. The
   random data generator was converted to use MR for scaling.
6) Add a cluster abstraction to run data loading for #5 on a
   remote or local cluster. This also moves and consolidates some
   Cloudera Manager utilities that were in the stress test.
7) Cleanup the wrappers around impyla. That stuff was getting
   messy.
