We now no longer write containers.conf, instead system connections and farms are written to a new file called podman-connections.conf. This is a major rework and I had to change a lot of things to get this to compile again with my c/common changes. It is a breaking change for users as connections/farms added before this commit can now no longer be removed or modified directly. However because the logic keeps reading from containers.conf the old connections can still be used to connect to a remote host. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
