As part of adding multiversion testing for repl and sharding, there was some blacklisting code that was added to burn_in_tests that was specific for these suites in order to blacklist tests that behaved differently between Mongo version (for example while a bug fix is waiting for a backport).

However, burn_in_tests is probably not the correct place for this blacklisting logic to live. By putting the logic in burn_in_tests, we are effectively saying that the tests are unstable, not that the tests have inconsistencies between versions. It might make more sense to put the logic in resmoke, which burn_in_tests is already using to get the list of tests to run and is already doing some blacklisting.
