Introduces OverrideHelpers object with convenience methods for inspecting certain aggregation and map-reduce commands, as well as overriding startParallelShell(), Mongo.prototype.runCommand(), and Mongo.prototype.runCommandWithMetadata(). Also removes a number of tests that were incorrectly blacklisted from the read_concern_majority_passthrough.yml and read_concern_linearizable_passthrough.yml test suites.
