Re-implement all PATCH APIs for user status

[lakshayman]

Issue Description

We are re-implementing the way we store user status. So for that, we have to update the four PATCH APIs /users/status/self, /users/status/update, /users/status/batch and /users/status/:userId according to the design doc https://docs.google.com/document/d/11kQ9MZ6gNjQ1EW9eruWWi8JeAjkIFLrWJ3s7rYVLEqc/edit?usp=sharing.

Expected Behavior

Update the user status in the new collection.

Current Behavior

Updating the user status in an old collection without storing change events.
