 * This function will extract the integrations that have been defined for either grafana managed contact point
 * or vanilla Alertmanager receiver.
 *
 * It will attempt to normalize the data structure to how they have been defined for Grafana managed contact points.
 * That way we can work with the same data structure in the UI.
 *
 * We don't normalize the configuration settings and those are blank for vanilla Alertmanager receivers.
 *
 * Example input:
 *  ```
 * { name: 'my receiver', email_configs: [{ from: "foo@bar.com" }] }
 * ```
 *
 * Example output:
 *  ```
 * { name: 'my receiver', grafana_managed_receiver_configs: [{ type: 'email', settings: {} }] }
 * ```
