Restructure UI in terms of Resources and Models

 - Display resources first
 - Then display models that are not mapped to resources

Main purpose is to pull forward the resources which are most critical in the
services we are building
Hyperlink parameter types (for models and primitives)
Remove top level list of models/resources (just use a flat list of all)

 - Top list is redundant with left nav
Move codegen links to left library
Hide operation details by default
Remove duplicate resource list in nav bar
Update documentation
Hyperlink model types
Add DELETE /organizations. Consolidate soft delete to SoftDelete class
Add validation that a specific model is mapped to at most one resource
Add getByGuid and document other enpoints for User resource
Fix hyperlink to model type in responses
Consolidate accept/review of membership requests directly into Membership Requests controller

 - Makes membership_request_review an internal implementation detail
