Create Organization type schema and API

Purpose/Overview:

UXPROD-2553 requires that we create a 'Organization type' schema and a CRUD API for these types.

Requirements/Scope:

1. Create organization_type and organization_type_collection schema
2. Create examples for these schemas
3. Add organizationTypes property to the organization schema
4. Implement CRUD API for organization types

   /organizations-storage/organization-types

5. Define indexes and foreign keys (to forbid deletion if type is connected to an organization)
6. Write API tests
7. Update acq-models in mod-organizations
8. No predefined organization types

There is no need to store the type name with the organization record, as filtering is possible with an UUID and there is no requirement for being able to search/sort by organization type.

Approach:

Acceptance criteria:

• Requirements are fulfilled
