    [queens-only] Rename the systemctl-daemon-reload exec

    While rebasing puppet-rabbitmq due to other reasons, I noticed that the
    undercloud (re) deploy would fail with:

    2019-05-31 09:59:00,919 INFO: Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: Exec[systemctl-daemon-reload] is already declared in file /etc/puppet/manifests/puppet-stack-config.pp:99; cannot redeclare at /etc/puppet/modules/systemd/manifests/systemctl/daemon_reload.pp:5 at /etc/puppet/modules/systemd/manifests/systemctl/daemon_reload.pp:5:3 at /etc/puppet/modules/rabbitmq/manifests/config.pp:231 on node undercloud-0.redhat.local
    2019-05-31 09:59:00,982 INFO: + rc=1

    This is because a newer puppet-rabbitmq introduced:
    +
    + if $::facts['systemd'] {
    + Class['systemd::systemctl::daemon_reload'] -> Service['rabbitmq-server']
    + }
       }

    Which then pulls in the exec called 'systemctl-daemon-reload' from the
    systemd module which conflicts with the same call we do in undercloud
    puppet manifest.
    Let's just rename this exact to 'systemctl-daemon-undercloud' so we do
    not duplicate this resource ever. Tested this on a queens undercloud
    with a puppet-rabbitmq that triggers the problematic exec and got a
    correctly redeployed undercloud.

    We could have used the systemd module instead but that might require
    other backports and this seems the smallest possible approach to solve
    this.
