Subject: [PATCH] Convert hardcoded regexes to raw strings for py36

From the Python 3.6 release notes:

A backslash-character pair that is not a valid escape sequence now
generates a DeprecationWarning. Although this will eventually become a
SyntaxError, that will not be for several Python releases. (Contributed
by Emanuel Barry in bpo-27364.) [1]

This patch converts the remaining regexes in the ovs plugin to raw.
