When a new user is created, two things happen:
- before inserting into MongoDB, the organizational roles are given
- after inserting, the organizations are updated to move the user from
`unknown_members` to `members`.
With a PATCH request you can now:
- assign users,
- remove a user,
- edit the name, description, and website fields.
Only the organization admin user can do this.
This is a Flamenco/Attract-style Manager object that's instantiated by
the PillarApplication. It can create Organizations and assign/remove
users.
Also I updated the Organization schema to reflect the currently desired
design.
NOTA BENE: this does not include any security/authorisation checks on Eve's
organizations collection.
