Currently, the commands `rhoas service-account create` and `rhoas service-account reset-credentials` support the file-formats "env", "json", "properties", "secret".

rhoas cli should have the ability to generate java properties files suitable for the Java Kafka Client.

Example properties file for Java Kafka client:

sasl.mechanism=OAUTHBEARER
security.protocol=SASL_SSL

sasl.oauthbearer.token.endpoint.url=https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token

sasl.jaas.config=org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required \
clientId="<client-id>" \
clientSecret="<client-secret>" ;

sasl.login.callback.handler.class=org.apache.kafka.common.security.oauthbearer.secured.OAuthBearerLoginCallbackHandler

Java Kafka Client properties format is central to Kafka and it will enhance the experience of Kafka Quickstarts.
