The following tests have been identified as bottlenecks and we would like to dynamically split them.

• concurrency_sharded_multi_stmt_txn_terminate_primary
• concurrency_sharded_multi_stmt_txn_kill_primary
• concurrency_replication
• concurrency_replication_wiredtiger_cursor_sweeps
• concurrency_sharded_terminate_primary_with_balancer
• concurrency_sharded_kill_primary_with_balancer
• aggregation_secondary_reads
• replica_sets_reconfig_jscore_passthrough
• replica_sets_multiversion

As a server engineer,
I want the listed test dynamically split when running in evergreen,
So that I can have smaller patch runtimes..

AC:

• The tasks listed above are split into subtasks when running in evergreen.
