Add ownerGroupId to CreateRecordSet endpoint

[britneywright]

In support of the new shared zones feature coming to VinylDNS we need to add the optional ownerGroupId field to the RecordSet create method.

Example Request:

{
  "name": "foo",
  "type": "A",
  "ttl": 300,
  "records": [
    {
      "address": "10.10.10.10"
    }
  ],
  "zoneId": "2467dc05-68eb-4498-a9d5-78d24bb0893c",
  "ownerGroupId": "f42385e4-5675-38c0-b42f-64105e743bfe"
}

See api docs at https://www.vinyldns.io/api/create-recordset.html

Expected Changes

• Add ownerGroupId to the recordset model at https://github.com/vinyldns/vinyldns-java/blob/master/src/main/java/io/vinyldns/java/model/record/set/RecordSet.java#L42. Note this field can be null.
• Update RecordSetBase to accept an ownerGroupId https://github.com/vinyldns/vinyldns-java/blob/master/src/main/java/io/vinyldns/java/model/record/set/RecordSetBase.java
• Update CreateRecordSetRequest to accept ownerGroupId https://github.com/vinyldns/vinyldns-java/blob/master/src/main/java/io/vinyldns/java/model/record/set/CreateRecordSetRequest.java
• add a createRecordset test that validates a create with a valid ownerGroupId passes. See https://github.com/vinyldns/vinyldns-java/blob/master/src/test/java/io/vinyldns/java/VinylDNSClientTest.java#L320 for an example. Note that the user must be in the group in order for the create to pass. Once created, get the recordset and validate that it has ownerGroupId = [id]. Note that you may need to add a mocked RecordSet for this (mocks are at the bottom of the test file, see https://github.com/vinyldns/vinyldns-java/blob/master/src/test/java/io/vinyldns/java/VinylDNSClientTest.java#L755)
