Add organization id to the provider.

Use the change in grafana/grafana-api-golang-client#9 to
apply an organization id to the provider.

Usage might look like this:

```hcl
provider "grafana" {
  url = "someurl"
  auth = "adminuser:somepass"
}

resource "grafana_organization" "neworg" {
  name = "neworg"
  admin = "neworgadmin"
}

provider "grafana" {
  alias = "neworg"
  url = "someurl"
  auth = "neworgadmin:somepass"
  org_id = grafana_organization.neworg.org_id
}

resource "grafana_data_source" "neworg_graphite" {
  provider = grafana.neworg
  type = "graphite"
  name = "neworg-graphite"
}
```
