* Allow priority attribute of dnsimple_record to be set
Some DNS record types (like MX) allow a priority to specified, and the
ability to do so is important in many environments.
This diff will change dnsimple_record.priority from computed to
optional, allowing it to be used in terraform configs like so:
resource "dnsimple_record" "mx1" {
domain = "example.com"
name = ""
value = "mx1.example.com"
type = "MX"
priority = "1"
}
resource "dnsimple_record" "mx2" {
domain = "example.com"
name = ""
value = "mx2.example.com"
type = "MX"
priority = "2"
}
* mention new priority attribute of dnsimple_record
* add acceptance specs for creating/updating MX records at dnsimple
