Fix the tripleo job definition

This patch redefines the puppet-octavia-tripleo-standalone job based on
tripleo-ci-centos-8-scenario010-standalone, to fix the tripleo
standalone job currently broken.
The difference between puppet-octavia-tripleo-standalone and
tripleo-ci-centos-8-scenario010-standalone is that we use
tripleo-puppet-ci-centos-8-standalone as its base job so that we can
make all tripleo jobs in puppet projects non-voting in a single place.
