JOC Cockpit setup should copy external JDBC driver to $JETTY_BASE/lib/ext/joc

Current Situation

• If JOC Cockpit is configured with a MySQL or MSSQL Server dbms then a MariaDB or respective a jTDS JDBC driver is provided by the setup.
• If a original JDBC driver from MySQL or MSSQL Server will be used then it has to copy to $JETTY_BASE/lib/ext/joc manually.

Desired Behavior

• You can enter the location of an external JDBC driver during the setup.
• The installer copies it to $JETTY_BASE/lib/ext/joc automatically.
