Moves undercloud upgrade introspection data migration to step 1

This moves the ironic introspection data migration from swift
to dbase to step1 of upgrade_tasks. It was previously in step3 but
that caused related-bug since mysql is down at that point. Needed
by [1] to fix the failing undercloud-upgrade job.
