**Issue** `Label` implements `Comparable` but it doesn't implement `.equals(Object o)` and `.hashCode()`. **Code** https://github.com/prometheus/client_java/blob/main/prometheus-metrics-model/src/main/java/io/prometheus/metrics/model/snapshots/Label.java **Test** ``` Label label1 = new Label("foo", "bar"); Label label2 = new Label("foo", "bar"); assertTrue(label1.equals(label2)); ```
