Add new compatibility_max configuration option

    Details

    • Sprint:
      Storage Non-NYC 2018-06-04, Storage Non-NYC 2018-06-18
    • Backport Requested:
      v4.0, v3.6

      Description

      MongoDB will need the ability to specify a compatibility window moving forward. That is the minimum and maximum compatibility versions of WiredTiger it can work with. That's required because otherwise a WiredTiger backport could cause compatibility checks to stop working, and for database format versions to change.

      We should extend the compatibility=(requires_min=) to also include a requires_max setting, and implement checking that database files weren't generated by a database newer than the defined maximum.
