Currently, multiversion tests are using master-4.3.4 binaries with FCV4.2. Since we are currently in the process of removing FCV4.2 behavior from master, we expect some multiversion passthroughs to break since the 4.3.4 binaries will still be using FCV4.2.

We will disable the multiversion passthroughs on master until the FCV is bumped to 4.6 since we won't getting meaningful test coverage from "multiversion passthroughs" using master-4.3.4 on FCV44. These test suites should be re-enabled promptly once the FCV has been bumped to 4.6.
