This patch adds support for IPv6 metadata service in ML2/OVN. The changes include: - Add the 'fe80::a9fe:a9fe/128' address to the interface of the ovnmeta- namespace so that it's reachable from the guests - Identify the port of the VM by looking up the source MAC address of the metadata request - Restarts the haproxy instances to honor the configuration changes upon start of the metadata agent. In particular, haproxy now also binds on the 'fe80::a9fe:a9fe' address When the VM requests metadata from its LLA, the traffic will reach the ovnmeta namespace associated to its network. The IPv6 metadata tests are passing and enabled in Tempest by this patch: https://review.opendev.org/c/openstack/neutron-tempest-plugin/+/894027 Besides, this patch ensures that the link-local address of the metadata interface is present so that the metadata IPv6 endpoint is reachable. It also fixes a bug that was causing the wrong LLA to be present as the interface was set `up` first prior to changing the MAC address. Now this order is inverted so that the proper LLA is configured. Change-Id: Idcef6de33ed2a73cb3c426db1c55fa9cd06de63f Signed-off-by: Daniel Alvarez Sanchez <dalvarez@redhat.com>
