 Description   

We have a lot of passthrough suites that enable a few flags just to obtain test coverage of certain cluster configurations that should not affect test correctness.

We now have a fuzzer in resmoke to fuzz setParameters for mongod --fuzzMongodConfigs. We can remove a lot of these passthroughts by fuzzing these parameters instead.

Here's a list of low-value passthough suites I think could be replaced:

Let's also try to get rid of some of the max_mirroring and large_txns suites since those parameters are now being fuzzed in SERVER-70759.

Max left a comment here suggesting some other passthroughs we could get rid of: https://github.com/10gen/mongo/pull/12293#discussion_r1172494242

After SERVER-70759, all that remains is the flow control passthrough. We might want to do this before so we feel more comfortable removing these suites: SERVER-76414. Specifically, it would be nice to have a jstestfuzz and config_fuzzer mashup.
