Nameservers added via /v2/pools are not validated

[Tim Simmons]

Nameservers in the /v2/pools API can be passed without being proper hostnames.

PATCH /v2/pools/id

{
  "pool":{
    "nameservers":[
      "ns1.test.com",
      "ns2.test.com"
      ]
  }
}

Will work just fine when there should be a trailing dot.

    Nameservers added via /v2/pools are not validated

    Use the correct validator for hostname to prevent nameservers with
    improper hostnames from getting to the database.
