OpenStack preferences

- [ ] Profiles page
- [ ] OpenStack profile endpoints

Do we want to mash OpenStack with the AWS user endpoint extensions? e.g.: 

```
GET    /user/{id}/os/profiles
POST   /user/{id}/os/profiles
PATCH  /user/{id}/os/profiles/{profileId}
DELETE /user/{id}/os/profiles/{profileId}
GET    /user/{id}/os/profiles/{profileId}/status
etc....
```
