Upgrade go-connlimit to v0.3.0 / return http 429 on too many connections (#8221)
Fixes #7527

I want to highlight this and explain what I think the implications are and make sure we are aware:

* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
  1) `conn.SetDeadline(10*time.Millisecond)` so that
  2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and 
  3) `conn.Close` can happen

The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.
