Add changelog for the v1.0.2 release
# Changelog
+# [v1.0.2](https://github.com/kubermatic/kubeone/releases/tag/v1.0.2) - 2020-09-02
+
+## Changed
+
+### Updated
+
+* Update machine-controller to v1.17.1 ([#1086](https://github.com/kubermatic/kubeone/pull/1086))
+ * This machine-controller release uses Docker 19.03.12 instead of Docker 18.06 for worker nodes running Kubernetes 1.17 and newer.
+ * Due to an [upstream issue](https://github.com/kubernetes/kubernetes/issues/94281), pod metrics are not available on worker nodes running Kubernetes 1.19 with Docker 18.06.
+ * If you experience any issues with pod metrics on worker nodes running Kubernetes 1.19, provisioned with an earlier machine-controller version, you might have to update machine-controller to v1.17.1 and then rotate the affected worker nodes.
