adds multiline flag to regex test for search and match

This commit adds the multiline flag to the regexp search and match test
plugin.  It defaults to re.M = False for backwards compatibility.  To use
the multiline feature add multiline=True to the test filter

{{ config | search('^hostname', multiline=True) }}
