Which use case/requirement will be addressed by the proposed feature?

I am trying to start an embedded Debezium Engine in my Spring Boot application. I configure Spring Boot by giving it a property which contains the URL, ie. 
dbc:postgresql://127.0.0.1:5435/mydatabase. To start Debezium I need to split that URL to get to the properties I need (database.hostname, database.port, database.dbname).

It would be easier to just pass the URL to Debezium instead of the parts. 

Implementation ideas (optional)

I see io.debezium.connector.postgresql.connection.PostgresConnection uses a pattern based factory to create the jdbc url from the given properties. It should be possible to use a patternfactory or urlfactory based on the given properties. Use the url if given, otherwise use the other properties to create the url based on the pattern.
