Ryu plugin was marked deprecated in Juno.
This commit actually removes the code for Kilo.

We (Ryu team) recommend users to migrate to ofagent, on which
we aim to concentrate our development resources by this deprecation.

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.
