lineinfile combined with with_items was very inefficient for this task. Given that each node's hostkey is added to every other host, it resulted in O(n²) performance. Additional networks per node also worsened the problem. For example, in a 100 node deployment, with 4 networks per node, this task would need to be executed 40,000 times (100 * 100 * 4). Switching to use blockinfile brings the performance back to O(n), and also removes any dependency on the number of networks per node. Change-Id: Id51d27f53abf3421c29a11065377e9303ad68d79
