POST /orgs/{id}/services/{id}/search doesn't account for nodes running an IBM service

[sf2ne]

This fix involves multiple steps:

• move POST /orgs/{id}/services/{id}/search to NodesRoutes.scala
• rename route to POST /v1/orgs/{orgid}/search/nodes/service where {orgid} is always the orgid of the user sending the request
• change the input body to be { "orgid": "string", "serviceURL": "string", "serviceVersion": "string", "serviceArch": "string" }
• change filter so that nodes are checked to be in org of user not org of service
• move over the unit tests to NodesSuite.scala and edit them to work with new input body
• add unit tests to test specifically the case of IBM services running on user-cluster nodes

Using this request body:

{
  "orgid": "major-peacock-icp-cluster",
  "serviceURL": "ibm.helloworld",
  "serviceVersion": "1.0.0",
  "serviceArch": "amd64"
}

Test 1: Searching a service running on 1 node

Sadiyahs-MacBook-Pro:~ sadiyahfaruk$ curl -X POST "https://9.30.210.34:8443/ec-exchange/v1/orgs/major-peacock-icp-cluster/search/nodes/service" -H "Authorization:Basic <user-auth>" -H "accept: application/json" -H "Content-Type: application/json" -d "@<path-to-file>/service_search_test.json"

{"nodes":[{"major-peacock-icp-cluster/<node1>":"2019-09-17T19:25:21.454Z[UTC]"}]}

Test 2: Add another node running that service to showcase 2 nodes

Sadiyahs-MacBook-Pro:~ sadiyahfaruk$ curl -X POST "https://9.30.210.34:8443/ec-exchange/v1/orgs/major-peacock-icp-cluster/search/nodes/service" -H "Authorization:Basic <user-auth>" -H "accept: application/json" -H "Content-Type: application/json" -d "@<path-to-file>/service_search_test.json"

{"nodes":[{"major-peacock-icp-cluster/<node1>":"2019-09-17T19:25:21.454Z[UTC]"},{"major-peacock-icp-cluster/<node2>":"2019-09-19T16:16:59.038Z[UTC]"}]}

Using this request body:

{
  "orgid": "major-peacock-icp-cluster",
  "serviceURL": "fake.service",
  "serviceVersion": "1.0.0",
  "serviceArch": "arm"
}

Test 3: Service running no nodes

Sadiyahs-MacBook-Pro:~ sadiyahfaruk$ curl -v -X POST "https://9.30.210.34:8443/ec-exchange/v1/orgs/major-peacock-icp-cluster/search/nodes/service" -H "Authorization:Basic <user-auth>" -H "accept: application/json" -H "Content-Type: application/json" -d "@<path-to-file>/service_search_test.json"
