Deploy Changes without restarting mongod/mongos instance immediately.
Whenever we want to make changes, eg. set a new parameter or add new parameter in configuration (advance configuration options), after we save changes, review and deploy, automation immediately starts applying that change and does a rolling restart.
We need flexibility in restart, means one should have an option to perform immediate rolling restart or defer it to later time. We may apply multiple changes at different times and set one preferred window to restart instance instead of doing multiple restarts.

Even in RDBMS world we have an option to defer the DB restart Its justified to request same functionality with better matured NOSQL features
We need this feature to schedule our changes when we have lower workloads.
