The mongo go driver dropped support for 2.6 in 1.11.0

https://github.com/mongodb/mongo-go-driver/tree/v1.11.0

We should probably drop support as well going forward as it is a fairly dated release at this point. Was mostly supported during the development to support default installations of some popular OSes.

Looks like mongo dropped support for versions < 3.6. I think we'll need to do the same in order to upgrade the driver.

Looks like anything prior to 4.2 is EOL already. 4.0 went EOL earlier this year, so it seems reasonable to retain support for that, but I'm thinking we should drop 3.x entirely.
