unlimited storage consumption by an Admin of any organization

[ElectricNroff]

An Admin of any organization can create many users with very large values of name fields (such as first name), limited mainly only by the permitted request rate. For many organizations, limits such as 100 users, and 100 characters per name field, would not interfere with their operations. Absence of limits on the amount of user data is potentially problematic for performance/usability reasons, e.g., when the Secretariat wants to call

GET /org/{shortname}/users

but also because of https://aws.amazon.com/documentdb/pricing/

Adding a small note to this while I am working on it.

Current live data:
Largest username length: 44 (I now notice this ticket is talking about the other name fields, username already has a 128 limit)
Largest number of users in an org: 29

Thoughts: The recommended 100 / 100 mentioned above sounds extremely reasonable. Will move forward with those numbers for now.
