Title: Add notes to rax_dns and rax_dns_record to recommend using serial: 1

This pull request addresses #7492 in that the API limit for the Rackspace CloudDNS API can easily be exceeded due to the way that API works.

The recommendation is to use `serial: 1` in plays utilizing the `rax_dns` and `rax_dns_record` to avoid exceeding the API limits.
