Description of problem:

We are using RHOSP8 beta9. When we set NeutronEnableL3Agent to false in the environment file, a vanilla openstack deployment will fail with following error messages on the openstack controller node.

Error: Could not find dependency Pacemaker::Resource::Service[neutron-l3-agent] for Pacemaker::Constraint::Base[neutron-dhcp-agent-to-l3-agent-constraint] at /var/lib/heat-config/heat-config-puppet/ef134cbc-5127-4388-b149-7354bdab2860.pp:1414\u001b[0m\n", "deploy_status_code": 1} 

The problematic code is as following.

if hiera('neutron::enable_dhcp_agent',true) and hiera('l3_agent_service',true) {
      pacemaker::constraint::base { 'neutron-dhcp-agent-to-l3-agent-constraint':
        constraint_type => 'order',
        first_resource  => "${::neutron::params::dhcp_agent_service}-clone",
        second_resource => "${::neutron::params::l3_agent_service}-clone",
        first_action    => 'start',
        second_action   => 'start',
        require         => [Pacemaker::Resource::Service[$::neutron::params::dhcp_agent_service],
                            Pacemaker::Resource::Service[$::neutron::params::l3_agent_service]]
      }
      pacemaker::constraint::colocation { 'neutron-dhcp-agent-to-l3-agent-colocation':
        source  => "${::neutron::params::l3_agent_service}-clone",
        target  => "${::neutron::params::dhcp_agent_service}-clone",
        score   => 'INFINITY',
        require => [Pacemaker::Resource::Service[$::neutron::params::dhcp_agent_service],
                    Pacemaker::Resource::Service[$::neutron::params::l3_agent_service]]
      }
    }

The problem is that hiera 'l3_agent_service' returns nil, do I miss something or the if condition in the above code is not correct?
