Describe the bug
When retrieving the data source for a region, the resource has a number of null fields that should be populated with data, such as the name of the region. When querying the region directly against the API, those fields show data...

An example output of a region's data source from the provider:

usw2 = {
  "cloud_account_id" = "6619bc9a18940e75-7f703c5265a63d87-e832bab19657dbecd082d308b9191fc68dc845ecbaedd055908d3cfd7a2bcc4a-9d401654141d487558a728a12fbb9"
  "created_at" = tostring(null)
  "external_region_id" = tostring(null)
  "filter" = tostring(null)
  "id" = "223cd589ed5cf27558a728a2c2130"
  "name" = tostring(null)
  "org_id" = tostring(null)
  "owner" = tostring(null)
  "region" = "us-west-2"
  "updated_at" = tostring(null)
}

That same region directly via the API:

{
  "externalRegionId": "us-west-2",
  "name": "us-west-2",
  "cloudAccountId": "6619bc9a18940e75-7f703c5265a63d87-e832bab19657dbecd082d308b9191fc68dc845ecbaedd055908d3cfd7a2bcc4a-9d401654141d487558a728a12fbb9",
  "id": "223cd589ed5cf27558a728a2c2130",
  "updatedAt": "2019-06-03",
  "organizationId": "fa57fef8-5d0e-494b-b299-7e4a9030ac11",
  "orgId": "fa57fef8-5d0e-494b-b299-7e4a9030ac11",
  "_links": {
    "self": {
      "href": "/iaas/api/regions/223cd589ed5cf27558a728a2c2130"
    },
    "cloud-account": {
      "href": "/iaas/api/cloud-accounts/6619bc9a18940e75-7f703c5265a63d87-e832bab19657dbecd082d308b9191fc68dc845ecbaedd055908d3cfd7a2bcc4a-9d401654141d487558a728a12fbb9"
    }
  }
}

To Reproduce

1. Create a "vra_region" data source
2. Create an output resource for the region data source
3. Query the vRA IaaSRegions API and confirm missing fields

Expected behavior
I would expect the provider to not be returning null values if values do exist for those fields....

@stvkpln Merged the PR #352. This will populate org_id and updated_at.

However, to populate owner and created_at, requires changes in the API. So, marking this as product issue
