Test and consider exposing different compression engines for MongoDB users

The WiredTiger storage engine supports several compression engines that are not exposed via MongoDB. It would be interesting to know whether there is value in exposing additional compression engines - it would also be very valuable to create a test that could be used to measure the relative compression rate vs CPU usage characteristics of different compression engines for a few interesting MongoDB workloads.

The particular compression engines that might be interesting are LZ4 and zstandard. A full set of compression libraries supported by the WiredTiger team is here:
