    Make Horizon get Neutron related parameters from Hiera

    Current implementation of horizon class in puppet-horizon
    holds well defined template for /etc/openstack_dashboard/local_settings.py
    that merges default neutron options with user defined options.
    Unfortunately only one user defined option "enable_distributed_router"
    gets its value from hiera, so we need to add ability to configure all
    available parameters using hiera.
