armband: Fix Fuel collect job reference

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.
