Exposes an additional logger that uses the test's root logger as the
parent for any TestCase instances constructor by the hook. The fixture
logger still continues to be the parent of the hook logger.
Also changes the CleanEveryN hook to explicitly get marked as a failure
if a ServerFailure exception is thrown, rather than relying on
TestReport.combine() to do so implicitly.
Split out the passthrough tests into separate suites. The MongoDB
deployment is started up by resmoke.py so that we can record the
success/failure of each individual test in MCI.
Added support for parallel execution of tests by dispatching to
multiple MongoDB deployments.
Added support for grouping different kinds of tests (e.g. C++ unit
tests, dbtests, and jstests) so that they can be run together. This
allows for customizability in specifying what tests to execute when
changes are made to a particular part of the code.
