Description
In order to specify sensitive settings that should not appear in the job configuration we support the creation and usage of a keystore file. Usually this keystore is created once with credentials and reused for each job that connects to Elasticsearch.
In some cases however, users may need to specify their job credentials at runtime when submitting jobs (#1633) as they may change frequently or for other requirements. We could document our KeystoreWrapper to support embedded creation of temporary keystores for said users.
