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:

• logical_session_cache_*_refresh (there are 13 of these tests with slightly different timeouts)
• concurrency_*_replication_wiredtiger_eviction_debug there are 2 of these
• concurrency_*_replication_wiredtiger_cursor_sweeps there are 2 of these
• jstestfuzz_*_flow_control: there are 5 of these with varying levels of flow control tickets
