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) }}
keeps backwards compat by not removing the previouslly non grammer matching states
and introduces new ones so user can decide which one he wants
(or keep both and still be inconsistent to annoy those that care)
