Signed webhooks

Outbound HTTPS notices of catalog changes, minimized and signed with HMAC-SHA256.

Register a webhook for some or all events. Events are named <resource>.<action>, such as service.created or vcs_tenant.updated. Each delivery carries only the type, action, id, name and time of the change.

Deliveries are signed over timestamp.body and sent in the X-YP-Signature header as sha256=<hex>. URLs must be public HTTPS: private addresses and special hostnames are refused. A test delivery and a per-webhook delivery log are available, and webhooks are private to their owner by default.
