Enabling DNS split authority with OctoDNS

Introduced OctoDNS, a tool for managing DNS records across multiple providers. This enables split authority for zones by synchronizing records between providers (e.g., Dynect and Route53) using configuration files stored in Git and a GitHub Flow-like workflow. The tool supports previewing changes ('noop' deploys) and executing them with a `--doit` flag, bringing Infrastructure as Code principles to DNS management.
