deployment fails with "Pcmk_bundle[haproxy-bundle]: Munging failed for value \"\" in class promoted_max: promoted_max must be an integer"

Seems like this popped up after https://review.opendev.org/c/openstack/puppet-pacemaker/+/840966 was merged.

There seem to be a few issues here:

1. haproxy-bundle uses replicas instead of promoted_max or masters (not really an issue per se):

https://github.com/openstack/puppet-tripleo/blob/master/manifests/profile/pacemaker/haproxy_bundle.pp#L286

and so both promoted_max and masters are undef.

2. pick_default coerces undef into an empty string (https://tickets.puppetlabs.com/browse/MODULES-11018)

3. https://github.com/openstack/puppet-pacemaker/blob/master/manifests/resource/bundle.pp#L159-L173 assumes either promoted_max or masters (or both) are defined but doesn't account the case where both are undef, like for haproxy-bundle.
