Add support for templating master admissionConfig.
Adds four new inventory variables for setting sections in "admissionConfig" and "kubernetesMasterConfig.admissionConfig". openshift_master_admission_plugin_order allows configuring the list of origin admission controller plugins to enable and what order to run them in. This must be a JSON formatted list of strings: openshift_master_admission_plugin_order=["RunOnceDuration", "NamespaceLifecycle", "OriginPodNodeEnvironment", "ClusterResourceOverride", "LimitRanger", "ServiceAccount", "SecurityContextConstraint", "ResourceQuota", "SCCExecRestrictions"] openshift_master_kube_admission_plugin_order is identical but for the kubernetes admission controller plugins which appear beneath kubernetesMasterConfig. openshift_master_admission_plugin_config allows setting free-form configuration stanzas that match up with enabled admission controller plugins. This must be a JSON formatted hash: openshift_master_admission_plugin_config={"RunOnceDuration":{"configuration":{"apiVersion":"v1","kind":"RunOnceDurationConfig","activeDeadlineSecondsOverride":3600}},"ClusterResourceOverride":{"configuration":{"apiVersion":"v1","kind":"ClusterResourceOverrideConfig","limitCPUToMemoryPercent":200,"cpuRequestToLimitPercent":6,"memoryRequestToLimitPercent":60}}} openshift_master_kube_admission_plugin_config is the equivalent for kubernetes admission controller plugins. Contains a change to merge_facts to fix issues with modifying inventory variables that contain JSON dicts. If you modified a previously set variable, the result would be a merge of old and new, which is completely wrong in this case. Addded new overwrite_facts to shortcut to just taking the new values. This differs from the pre-existing concept of "protected" in that we're not protecting an old value, we're trashing it and taking the new.
