GenerateNodeService returns a new External corev1.Service pointer generated for the given Solr Node.

GenerateSolrMetricsService returns a new corev1.Service pointer generated for the SolrCloud Prometheus Exporter deployment Metrics will be collected on this service endpoint, as we don't want to double-tick data if multiple exporters are runnning.

Utility struct holding security related config and objects resolved at runtime needed during reconciliation, such as the secret holding credentials the operator should use to make calls to secure Solr.

SolrConnectionInfo defines how to connect to a cloud or standalone solr instance.

Helper struct for holding server and/or client cert config This struct is intended for internal use only and is only exposed outside the package so that the controllers can access.
