add ability to expose Elasticsearch as an external route
This adds the ability to expose Elastisearch as a route outside of the cluster. - `openshift_logging_es_allow_external`: True (default is False) - if this is True, Elasticsearch will be exposed as a Route - `openshift_logging_es_ops_hostname`: The external facing hostname to use for the route and the TLS server certificate (default is "es." + `openshift_master_default_subdomain`) There are other similar parameters for the TLS server cert, key, and CA cert. There are other similar parameters for when the OPS cluster is deployed e.g. `openshift_logging_es_ops_allow_external`, etc.
