Test Open Distro for Elasticsearch

Open Distro for Elasticsearch appears to be compatible with the connector, but is not officially supported because we don't test it.

The docker image requires secure connections by default, and comes with a demo root CA certificate that must be imported into the trust store used by the connector. The default credentials are username=admin password=admin

The demo root CA certificate can be extracted from a running docker container:

docker cp <container_id_or_name>:/usr/share/elasticsearch/config/root-ca.pem es-root-ca.pem

keytool -importcert -file es-root-ca.pem -keystore my-trust-store.jks

When prompted for a keystore password, use password specified in secrets/truststore-password.toml.

Modify the [truststore] section of the connector config so path points to my-trust-store.jks. Modify the [elasticsearch] section so username = 'admin' and secureConnection = true. Modify the secrets/elasticsearch-password.toml file so password = 'admin'.
