Description of problem:
The endpoint information didn't be removed from haproxy.config when service and pod is deleted.
please note, first delete service and then delete pod.

I'm afraid at this time another people create one pod with IP is same as above pod

example:
user A create pod/service/route and assume pod ip is (10.129.0.2). now A delete service firstly and then delete pod. the route will cannot be accessed. but the endpoints information still exist in haproxy.config.

Check the haproxy.config:
<--snip-->
server 302789aed6899093dadb89a311076244 10.129.0.2:8080 check inter 5000ms cookie 302789aed6899093dadb89a311076244
<--snip-->

now user B create one pod and the pod IP is just to (10.129.0.2). 

then user A can access his route to user B's Pod
