An API for MoQ: provision your own isolated relays

Introduced a MoQ provisioning API that allows users to create isolated relays across Cloudflare's global network. This API supports draft-14 and draft-16 of the MoQ Transport protocol and enables the issuance of separate credentials for publishers and subscribers, providing access control and isolation for applications. The API manages relays and tokens, which are scoped to specific operations (publish, subscribe) and can have expiration and revocation. The post also details the integration of these features with the Cloudflare dashboard and provides examples using the moq-rs tools.
