Get roles list without dependencies using the API

[vanyarock01]

I have few cartridge roles in my app: router (depends on vshard-router) and storage (depends on vshard-storage).

If I try to get a list of replicasets roles, I get roles with dependencies.

$ curl -i -H 'Content-Type: application/json' -X POST -d '{"query": "query {replicasets { roles }}"}' localhost:8081/admin/api
HTTP/1.1 200 Ok
Content-length: 102
Server: Tarantool http (tarantool v1.10.3-136-gc3c087d)
Content-type: application/json; charset=utf-8
Connection: keep-alive

{"data":{"replicasets":[{"roles":["vshard-router","router"]},{"roles":["vshard-storage","storage"]}]}}

But, I need to get roles without dependencies.
