• Take caller and call initiation into consideration when performing persistence rate limiting.
• Caller is either system or user namespace name
• Call initiation is only defined when caller type is api and its value will be the frontend method name
• If caller is user namespace name (not system), the persistence call will first consume a per ns token and then a host level token.
• Specified caller and call initiation information

Why?

• System protection

• Will add more unit test.
• Will test locally.
