Add the ability to specify an interface about ddns-route53 HOT 4 CLOSED

@mhriemers Sure SGTM!

Alright, what would be the best way to implement this in your opinion? Since the IPv4 and IPv6 addresses are gathered only once and reused for all records, I'm thinking about an extra configuration item on the root (such as Interface) or a command flag. WDYT?

@mhriemers I think we can extend the configuration with a global section like:

global:
  interface: eth0

credentials:
  accessKeyID: "ABCDEFGHIJKLMNO123456"
  secretAccessKey: "abcdefgh123456IJKLMN+OPQRS7890+ABCDEFGH"

route53:
  hostedZoneID: "ABCEEFG123456789"
  recordsSet:
    - name: "ddns.example.com."
      type: "A"
      ttl: 300
    - name: "ddns.example.com."
      type: "AAAA"
      ttl: 300
    - name: "another.example2.com."
      type: "A"
      ttl: 600

You could then use:

ifaces, err := net.InterfaceByName(cfg.Global.Interface)
if err != nil {
	return err
}

addrs, err := ifaces.Addrs()
if err != nil {
	return err
}

// check each addr and retrieve first valid one?
// should exclude global unicast, multicast, loopback, etc.

In a follow-up we could also override the global interface for specific records.
