[multiple] Add LVMS support to dt-vhosts-compact and dt-sharded-compact

Add 3 extra disks (50G each) to OCP master nodes and configure LVMS
using /dev/vda, /dev/vdb, /dev/vdc, following the same pattern used
by other compact OCP scenarios (va-multi, dt-nfv-ovs-dpdk-sriov-hci).
This replaces the default ci_local_storage with the LVMS operator for
dynamic local storage provisioning.
