writeConflictRetry keeps snapshot open while backing off

Description:
Info
Our write conflict backoff logic sleeps before rolling-back the active transaction with abandonSnapshot(). This exists as far back as 4.4 where I checked. This can make write conflicts and cache pressure worse because transactions will stay active, potentially holding resources and are unkillable while they sleep.
