Update i18n translation for Cisco plugins and cfg agent log msg's

All the existing LOG.info, LOG.warning, LOG.error and LOG.critical
messages should have _LI, _LW, _LE and _LC respectively. Also, debug
level log shouldn't be translated. This patch set will cover the cisco
directory under neutron/plugins.
