resmoke.py cannot enable failpoints from commandline

      We can configure failpoints at startup with command line arguments thus:

      ./mongod --setParameter enableTestCommands=1  --setParameter failpoint.dummy='{ "mode" : "alwaysOn" }'

      So it should be possible to pass such command line args through resmoke.py, like:

      buildscripts/resmoke.py --mongodSetParameters '{"failpoint.dummy": {"mode": "alwaysOn"}}'

      This fails because resmoke doesn't know how to handle dotted parameter names when it generates the JavaScript that constructs TestData. Edited output:

      It tries to set TestData.setParameters.failpoint.dummy, but it hasn't created the "failpoint" property first.

      Either resmoke.py should create a TestData.setParameters property named "failpoint.dummy" with the dot included, or it should create a property named "failpoint" and then a property named "dummy", I'm not sure which.
