  - armband: Fix Fuel collect job reference

    Armband uses different 'pod' naming/labeling, so instead of Fuel's
    'baremetal' reference, we have 'armband-baremetal', leading to
    unresolved job references for the recently added log collection.

    Fix that by adding a new 'deploy-type' variable, which corresponds
    to either 'baremetal' or 'virtual', aligning with Fuel naming.
    While at it, slightly refactor our pod definitions to use the new var.
