Attempt to reduce cost with cloud functions calls

[JasonIsAzn]

Overview

There are two cloud functions that have high request, which is IsUserInBlackList and NotifyUpcomingEvents

On a Monday Afternoon with no events and no devs working on the app or website, there is a relatively large bandwidth usage and low numbers of reads. The only thing I can think of that would cause this is these two cloud functions.
It may or may not be the cause but would be a good idea to remove isUserInBlackList and decrease freq of NotifyUpcomingEvents

Task

• Remove Blacklist Checking
• Decrease freq of NotifyUpcomingEvents

Additional

If we see that blacklist is a major factor in the cost then we'll completely remove the feature in another ticket
