This patch introduces modularity into the default keepalived configuration: Currently, keepalived uses a ping to check its alive status. The IP was hard setted in the configuration file. This patch introduces multiple variables: - keepalived_ping_address - keepalived_ping_count - keepalived_ping_interval The one probably used the most will be the ``keepalived_ping_address``. It's therefore listed in ``user_variables`` with the other keepalived variables. Fixes-Bug: #1570420 Change-Id: Ic9a591fe739dd4ee3b0ad0130190e000404fb73a
