Ansible Keepalived

I have looked around at available keepalived roles on Github but none meet my expectation, so I create my own role here.

Priority, Weight will be automatically caculated based on number of nodes, VIPs and internal_priority settings. You only need to change all your variables in vars/main.yml. Try it and have fun^^.

PRs are welcomed

Requirements
