    Compute dashboard_frontend_vip according to the haproxy frontend
    
    When Ceph dashboard is deployed, the mgr plugin is enabled on the
    storage network, and, assuming that network is the value assigned
    to 'CephDashboardNetwork', we need to change the way the frontend
    vip is computed both in the standard scenario and when composable
    networks are provided via tht.
    The purpose of this change is to have a set of tasks to properly
    compute the 'dashboard_frontend_vip' variable using the hieradata
    generated for each service.
    When StorageNetwork is present, 'ceph_dashboard_vip' will be set
    and assigned to the haproxy frontend (because that's the network
    used to expose and access the dashboard components), but when the
    'ceph_dashboard_vip' ansible variable is not present, we can rely
    (as assumed before) on ctlplane network.
    This change is required to fix the tls-everywhere integration and
    it is still valid for standard deployments.
