post-scripts: Enable systemd-binfmt for first boot.
ARMBAND NOTE(S): - This is a bug fix + a new feature (arch list in a file on FM) - This is overengineered because: * we want to move patching to post-ISO creation, OPNFV style; * easier integration with Fuel@OPNFV, using post-install scripts; * prepare for true multiarch support on Fuel Master; IMPORTANT: This commit introduces the following file on Fuel Master, containing the list of arch supported for target nodes: </etc/fuel_openstack_arch>. This file is created AFTER pre.d OPNFV scripts are ran, also by bootstrap_admin_node.sh, BEFORE the post.d scripts are executed. NOTE: Arch format is the same used by dpkg (e.g.: "amd64 arm64") Based on the number of foreign architectures we should support (the list of archs in /etc/fuel_openstack_arch minus native arch), we determine whether cross-builds are expected, in which case binfmt support should be functional during first Fuel Master boot. Since systemd-binfmt service has a series of preconditions for starting, which are tested early during first boot, some of them are NOT YET true (e.g. no binfmt handlers are present before qemu-user-static package is installed), so the service is not automatically started. Of course, this only affects the first boot. Finally, this commit adds an OPNFV post-install script in /opt/opnfv/bootstrap/post.d, which starts systemd-binfmt service.

+Subject: [PATCH] post-scripts: Enable systemd-binfmt for first boot.
+
+IMPORTANT:
+This commit introduces the following file on Fuel Master,
+containing the list of arch supported for target nodes:
+</etc/fuel_openstack_arch>.
+
+This file is created AFTER pre.d OPNFV scripts are ran, also by
+bootstrap_admin_node.sh, BEFORE the post.d scripts are executed.
+NOTE: Arch format is the same used by dpkg (e.g.: "amd64 arm64")
+
+Based on the number of foreign architectures we should support
+(the list of archs in /etc/fuel_openstack_arch minus native arch),
+we determine whether cross-builds are expected, in which case
+binfmt support should be functional during first Fuel Master boot.
+
+Since systemd-binfmt service has a series of preconditions for
+starting, which are tested early during first boot, some of them
+are NOT YET true (e.g. no binfmt handlers are present before
+qemu-user-static package is installed), so the service is not
+automatically started. Of course, this only affects the first boot.
+
+Finally, this commit adds an OPNFV post-install script in
+/opt/opnfv/bootstrap/post.d, which starts systemd-binfmt service.
