* Add initial deSEC support * Handle the api rate limiting * Fix deleteRR and do some code cleanup * improve rate limiting and record deletion * Add documentation for deSEC provider * README.md update list of supported DNS providers * deSEC supports SSHFP records * dynamic minimum_ttl and hint for DNSSec on domain creation * merge all changes into one single bulk api request * Fix: actually set the TTL to min_ttl if necessary * use a constant for apiBase URL * Fix code comments * Use PUT instead of PATCH for upsertRR method * use ' instead of " for java script examples
