Just a little cleanup from an earlier patch that makes f5 unit tests only run if the f5 sdk is installed
This patch updates the bigip_pool module to use F5's REST API as well as includes unit tests. Unit tests are provided. Integration tests can be found here https://github.com/F5Networks/f5-ansible/blob/devel/test/integration/bigip_pool.yaml#L23 https://github.com/F5Networks/f5-ansible/tree/devel/test/integration/targets/bigip_pool/tasks
