  - [patch] cleanup: Drop LVM filter disable

    Now we explicitly add a LVM PV on /dev/sda{1,2} for Cinder storage,
    so we can safely drop the patch disabling LVM volume filtering.
    If we later move the PV to a different disk, we can just add the VG
    and LV definitions to linux:storage via reclass, and Salt will skip
    setting them up (as they're already created by MaaS), yet keep the
    filtering sane.

    While at it, fix 'nova_cpu_pinning' param expr; constructs based on
    reclass interpolation (e.g. '${_param:x}') do not work when
    parameters are passed via reclass.storage templating, so change
    reclass interpolation syntax with classic YAML anchors.

    Fixes: 672ae12
