[ Upstream commit 9d74da1177c800eb3d51c13f9821b7b0683845a5 ]
conncount has its own GC handler which determines when to reap stale elements, this is convenient for dynamic sets. However, this also reaps non-dynamic sets with static configurations coming from control plane. Always run connlimit gc handler but honor feedback to reap element if this set is dynamic.
