--- features: - | Two custom per-service hiera keys are added tripleo::haproxy::::internal_bind_options and tripleo::haproxy::::public_bind_options. They control additional custom options that can be added to the bind line of a specific service configuration in haproxy. One use case is to force older TLS versions for internal APIs that end up pointing to devices that do not support the latest TLS standard. They accept a single string or an array of strings.
