kong-app release v1.0.0

Kong Ingress Controller 1.0 removes support for several deprecated flags and the KongCredential custom resource. Please see the controller changelog for details. Note that Helm 3 will not remove the KongCredential CRD by default: you should delete it manually after converting KongCredentials to credential Secrets. If you manage CRDs using Helm (check to see if your KongCredential CRD has a app.kubernetes.io/managed-by: Helm label), perform the credential Secret conversion before upgrading to chart 1.11.0 to avoid losing credential configuration.
The chart no longer uses the extensions API for PodSecurityPolicy, and now uses the modern policy API. This breaks compatibility with Kubernetes versions 1.11 and older. (#195)
