With version 10.4.0 of cloud regionsrv-client a general way to handle billing model switches has been implemented. This supersedes the previous Azure specific implementation. In addition a billing model change feature is being introduced in GCE. Enable billing model switches in GCE using the new implementation and switch Azure to the new implementation. Feature is not supported for 3rd party listings (Marketplace images) or when no PAYG equivalent exists.
Depending on the protocol version for SSH we need to set either ChallengeResponseAuthentication or KbdInteractiveAuthentication to "no". Prior to this change we only set ChallengeResponseAuthentication allowing password based login when the SSHv2 protocol is used. We now modify newer config files appropriately.
cloud-init will be updated in distributions 15 SP4 and later. The new version has 2 new services. Enable the 2 new services in the imabe builds in preparation for the package update. This allows us to avoid having to synchronize image build description updates with he package version update. Signed-off-by: Robert Schweikert <rjschwei@suse.com>
