The MySQL Event Listener only allows for a single configuration property- the JDBC db URL. I recently encountered an issue where my password contained special characters that needed to be escaped or url encoded. However, this was difficult to get working because we can't supply the password as a separate config that gets passed. This is easily handled e.g. by the MySQL connector properties where i can set the user and password params as separate config properties like so:

connector.name=mysql
connection-url=jdbc:mysql://example.net:3306
connection-user=root
connection-password=secret

I would like to request that the mysql event listener similarly support these configs.
