Issue

Allow space application supporter to access specific route endpoints.

Context

We are introducing a new role and we want to make sure it has the right access.

Expected result

A space application support should be able access the following endpoints:

POST /v3/routes
GET /v3/routes
DELETE /v3/routes/:guid
GET /v3/domains/:guid/route_reservations
GET /v3/routes/:guid/destinations
GET /v3/apps/:guid/routes
POST /v3/routes/:guid/destinations
PATCH /v3/routes/:guid/destinations
DELETE /v3/routes/:guid/destinations/:destination_guid
DELETE /v3/spaces/:guid/routes?unmapped=true

Acceptance

A space application supporter would see the same info as a space developer assigned to the same space for these and only these routes endpoints.

Documentation

When I browse to any of these endpoints on v3 docs I can see the Space Application Supporter role in the list of permitted roles with an indication that this role is not fully implemented and the permissions will be changing.
