(Develop) Review API Updates Roles and Companies tables running avrage

[banushi-a]

The next subtask of this epic is to update these new values in the Roles and Companies tables when Reviews are 1) Added, 2) Updated, and 3) Deleted. We will need to update all three at once. One way we can ensure they are all added at once are using drizzle transactions. These operate on an "all or nothing" basis, so we can make sure the actual review averages and the values stored in the Roles and Companies tables stay in sync.
When we do this we will most likely need to wipe the database of all its reviews to make sure the running averages are actually in-line with the actual review averages.
