title: Ansible wait_for module, start at end of file
body: <p>With the <code>wait_for</code>module in Ansible if I use <code>search_regex='foo'</code> on a file</p>
  
  <p>it seems to start at the beginning of the file, which means it will match on old data, thus when restarting a process/app (Java) which appends to a file rather than start a new file, the <code>wait_for</code> module will exit true for old data, but I would like to check from the tail of the file.</p>
