Description

In order to break the cycle of some potential 3-way deadlocks involving index builds, prepared transactions, and step down, we will investigate not acquiring the RSTL for index build cleanup. Index build cleanup does not require synchronization with replica set state transitions. See ~~SERVER-42621~~ for description of a potential deadlock.
