Description of problem:
=======================
In stable/queens, we break since we don't feed ansible with any value.
We don't support or ship an Amphora image that is non-x86_64. The purpose of specifying the arch is (as stated here[1]) to hint the Nova scheduler which compute nodes to take into account when it schedules an Amphora instance.
