loadbalancer configuration is not updated when units are removed

[David Negreira]

When we have apache2 related to more units with the 'balancer' relation, the balancer configuration stays the same after deleting 1 of the 3 units as an example:

“ cat /etc/apache2/conf-enabled/kubernetes-worker.balancer.conf
<Proxy balancer://kubernetes-worker/>.
BalancerMember http://a.a.a.a:80 timeout=60
BalancerMember http://b.b.b.b:80 timeout=60
BalancerMember http://c.c.c.c:80 timeout=60

ProxySet lbmethod=byrequests
RequestHeader set X-Balancer-Name “kubernetes-worker”
</Proxy>.
“

Refreshes automatically only after adding another worker

“ cat /etc/apache2/conf-enabled/kubernetes-worker.balancer.conf
<Proxy balancer://kubernetes-worker/>.
BalancerMember http://a.a.a.a:80 timeout=60
BalancerMember http://d.d.d.d:80 timeout=60
BalancerMember http://c.c.c.c:80 timeout=60

ProxySet lbmethod=byrequests
RequestHeader set X-Balancer-Name “kubernetes-worker”
</Proxy>.
