Currently Doctrine's Oracle drivers do not distinguish between SID / SERVICE*NAME and DBNAME connection parameters which do not necessarily have to be the same in every database environment setup. The SID is the unique name of the database instance to connect to and can be superseded by a more general SERVICE_NAME which can be configured to contain multiple database instances in a HA environment on server side. For each individual database environment setup to work we need to be able to specify different values for SID / SERVICE*NAME and DBNAME.
This PR adds an additonal servicename connection parameter which is used instead of dbname for the SID / SERVICE_NAME connection parameters IF given. I also updated the docs to cover this and another parameter service which was introduced in DBAL-141 but never got documented.
