* Enable these checks in the default configuration file, which may produce many new results:
* automountServiceAccountToken
* linuxHardening
* sensitiveConfigmapContent and sensitiveContainerEnvVar
* clusterrolebindingClusterAdmin, rolebindingClusterAdminClusterRole, and rolebindingClusterAdminRole
* clusterrolePodExecAttach, rolePodExecAttach, clusterrolebindingPodExecAttach, rolebindingClusterRolePodExecAttach, and rolebindingRolePodExecAttach
* Ignore the `missingNetworkPolicy` and `automountServiceAccountToken` checks by default
* `hasPrefix` and `hasSuffix` functions are now available in the go template
* Fix the `sensitiveContainerEnvVar` check to ignore sensitive environment
variable names when those variables use `valueFrom` to reference an
external resource.
* Add the `*ClusterAdmin` checks to `examples/config-full.yaml`.
* Exempt the prefix `system:` instead of individual entries for RBAC checks (#871)
