SERVER-32522 Clean up {read,write}Concern and readPreference overrides.

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.
