Makes it so that a link to the logs for every test that ran is present
in the sidebar of the Evergreen UI. Multiple entries will appear for
the same test file when --repeat is used.
This also fixes an issue where the number of tests skipped would be
incorrect if the same test file was included multiple times in the
"roots" key.
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.
