    **Removed** legacy `EnvoyFilter` implementation for telemetry. For the majority of users, this change has no impact, and
    was already enabled in previous releases. However, the following fields are no longer respected: `prometheus.configOverride`,
    `stackdriver.configOverride`, `stackdriver.disableOutbound`, `stackdriver.outboundAccessLogging`.
