==== Jetty Metrics
Auto-configuration will bind metrics for Jetty's `ThreadPool` using Micrometer's `JettyServerThreadPoolMetrics`.
Metrics for Jetty's `Connector`s are bound using Micrometer's `JettyConnectionMetrics` and, in addition when configprop:server.ssl.enabled[] is set to `true`, Micrometer's `JettySslHandshakeMetrics`.
