    Make ::tripleo::profile::base classes work with multiple nodes

    In the Next Generation HA architecture a number of active/active services
    will be run via systemd. In order for this to work we need to make sure that
    the sync_db operation only takes place on the bootstrap node, just like it is
    done today for the pacemaker profiles.

    We do this by removing sync_db as a parameter and instead set it to true
    or false depending if the hostname matches the bootstrap_node as it is done
    today in the pacemaker role.

    Note that we call hiera('bootstrap_nodeid', undef) because if a profile
    is included on a non controller node that variable will be undefined.

    The following testing was done:
    - HA puppet-pacemaker.yaml scenario with three computes
    - NonHA with one controller
    - NonHA with three controllers
