Fix false alert messages in HAProxy logs

Browse Source 
Bug #1549753 raises false alarm about haproxy to the operator and
monitoring tools even though haproxy is running fine and there is
no issue.

haproxy uses UDP datagram socket for logging and the default queue
length of 10 datagrams causes false alert messages in haproxy
logs. This patch set fixes this bug by increasing the queue length
to 128.

Test results of the fix in this patch set are at
