HTTP/2 connection pool coordinator.

A gen_state_machine per origin that routes concurrent callers to available stream slots across one or more HTTP/2 connection workers. Opens new connections when all existing ones are at max_concurrent_streams. Queues callers when the connection count is also at the maximum.

The coordinator uses a two-phase caller model:

  1. Caller sends a gen_statem call to the coordinator (checkout phase).
  2. Coordinator forwards the request to a connection worker via message.
  3. The connection worker replies directly to the caller's from reference.
