[PATCH v2 1/1] UBUNTU: [Packaging] add a new migrate autogenerate option

[Timo Aaltonen]

From: Kleber Sacilotto de Souza <kleber.souza at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1991130

Add a new "migrate" command to be used by 'debian/package.config' which
contrary to "transitional" doesn't have the autogenerated contents
filtered out by 'debian/rules.in' depending on the source's variants.

v2: rebased, and added Provides which is needed to replace the old driver
