IOT-982 Query handling for /oic/res

IOT-982 Query handling for /oic/res

- By default oic.if.baseline is added for any resource created. All resource
  created in OIC should have oic.if.baseline.
- In case query is empty, oic.if.ll as interface query.
- oic.if.ll handler returns all resources which are DISCOVERABLE.
- Same handler handles when query includes oic.if.ll.
- Only oic.if.ll and oic.if.baseline are supported as query param for /oic/res.
- oic.if.baseline handler only responds to query that are baseline interface.
- In case query includes rt but no if param. response is based on matching of rt value.
- It also include rt, if and uri for /oic/res response if it is oic.if.baseline..
