Load balancer configurations using HAProxy

Ported from apache/cloudstack-primate#778

This is the UI change needed for confgiuring load balancer
rules using haproxy and also adding ssl certificated to
load balancer rules

Load balancer configs are avaiable at two scopes.
one at the network level under "LB Configs" tab and
another under each load balancer rule and can be configured
by clicking on "Configuration" button.

The SSL certificates can be added only for load balancer
rules with ssl protocols

To apply global load balancing configurations, navigate to "Networks" -> LB Configs
