The following test suites when run on the Enterprise RHEL 6.2, Linux DEBUG, and Enterprise Windows 2008R2 cause the makespan to exceed 1 hour. We should use the script from SERVER-34296 to split them into test suites that take no longer than 20 minutes in order to reap concurrency benefits by running on separate EC2 instances. The Evergreen tasks added to the etc/evergreen.yml project configuration should be done under a display task of the original name in order to limit the Evergreen UI differences Server team engineers would otherwise encounter.

• replica_sets_auth.yml (~1h on Enterprise Windows 2008R2)
• replica_sets_ese.yml (~1h on Enterprise Windows 2008R2)
• sharding.yml (~50m on Enterprise RHEL 6.2, ~1h20m on Linux DEBUG)
• sharding_auth.yml (~50m on Enterprise RHEL 6.2, ~1h10m on Linux DEBUG, ~1h40m on Enterprise Windows 2008R2)
• sharding_ese.yml (~50m on Enterprise RHEL 6.2, ~1h50m on Enterprise Windows 2008R2)
• sharding_last_stable_mongos_and_mixed_shards.yml (~50m on Enterprise RHEL 6.2)
• sharding_op_query.yml (~50m on Enterprise RHEL 6.2)
• sharding_auth_audit.yml (~45m on Enterprise RHEL 6.2, ~1h45m on Enterprise Windows 2008R2, but only runs after sharding_auth Evergreen task completes)

Note: The write_concern_majority_passthrough Evergreen task takes ~50m on Linux DEBUG; however, that seems more likely to be due to the removeb.js, mr1.js, remove9.js, geo_s2sparse.js, and queryoptimizer3.js tests taking longer than 15 minutes. We should look to modify these tests in a similar fashion to the changes in SERVER-33645 under a separate ticket.
