Set UpdateIdentifier for upgrade converge, to prevent services down

We'd like to let the post puppet pacemaker controller services
restart to happen for the convergence step so set the
UpdateIdentifier. However also set the PackageUpdate to noop so the
yum_update.sh doesn't happen.

Since a full haproxy restart is expected, we no longer need the
systemctl reload added at Iae3bad745ecdf952a7a0314fe1375d07eb47c454
so remove that too.
