  - Merge "[lib.sh] Reset virtual nodes after MaaS install"
  - [lib.sh] Reset virtual nodes after MaaS install

    For hybrid PODs (e.g. x86_64 jumpserver + control nodes, aarch64
    baremetal compute nodes), the virtual nodes rely on MaaS DHCP to be
    up when the OS boots, so issue a `virsh reset` accordingly.

    Instead of checking for online nodes using `test.ping`, use
    `saltutil.sync_all` to also sync Salt state modules to the virtual
    nodes (usually handled by baremetal_init state in HA deploys).
