Steps:
1. Create next cluster - HA, CentOS, Neutron Vlan, 3 controller, 2 compute nodes
2. Deploy cluster
3. Kill haproxy on node-1 - kill -9 $(pidof haproxy)
4. Create instance and assign floating ip to it
5. Ping floating ip

Expected - floating ip is pingable
Actual - it's not pingable

I also tried to ping internal instance ip through dhcp namespace but internal ip wasn't pingable too

Logs are attached

First of all you had to create security group rules, which allow to ping instances.
According to logs - you have not created them.
That's why you did not ping instances even via net namespaces.

I have gone through your steps - all is working, haproxy was started again after killing.
All instancess are piged by any way.
