github.com/reload/dnsimple-dk-hostmaster-ds-upload (go): Package function is a Google Cloud Function receiving webhook events from DNSimple (https://dnsimple.com/webhooks).  It reacts to `dnssec.rotation_start` and `dnssec.rotation_complete` events and passes the new DS record on to DK Hostmaster via their DS Update protocol (https://github.com/DK-Hostmaster/dsu-service-specification).  The cloud function needs to be configured through environment variables.  The `TOKEN` environment variable is the access token that should be added as URL query parameter to the trigger URL (e.g. `?token=abcdefeghijklmnopqrstuvxyz0123456789`).  The `DNSIMPLE_TOKEN` environment variable is a DNSimple API token that is used to retrieve DS records from DNsimple.  For the domains in your DNSimple account that you would like this cloud function to update in DK Hostmaster you need to add three environment variables. They should all be prefix with the Domain ID from DNSimple (e.g. 123456).  `123456_DOMAIN`: the (apex) domain name in DK Hostmaster.  `123456_USERID`: the DK Hostmaster handle you use to login to their self service.  `123456_PASSWORD`: the DK Hostmaster password you use to login to their self service.
