Commit ab38d167c40c99 causes federation loops for non-existent resources to
result in multiple temporary livelocks, each lasting for $DEBUGINFOD_TIMEOUT
seconds. Since concurrent requests for each unique resource are now serialized,
federation loops can result in one server thread waiting to acquire a lock
while the server thread holding the lock waits for the first thread to respond
to an http request.
An implementation for this PR should help protect against this behaviour. Ex.
if --forwarded-ttl-limit=0 then the timeout behaviour of local loops should be
avoided.
