Title: Adds support for updating A record based on its subdomain

The current route53_ddns.rb script assumes a zone contains a single A record. This pull request adds support for zones with multiple A records. It does this by adding a command line option called 'subdomain' that when specified, only updates the A record that starts with the specified string.

If the subdomain is not specified, the existing behaviour of assuming a single A record is used.
