Exposes a way to specify how jstests passed in on the command line
should be run. Defaults to starting a standalone mongod.
--executor=core_small_oplog_rs
is equivalent to smoke.py's --small-oplog-rs
--executor=no_server
is equivalent to smoke.py's --dont-start-mongod
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.
