Extended the ServiceStack framework test scenarios to perform all test scenarios using MySql, PostgreSql, and Sql Server with ORMLite

1. Fixed an issue with the MySql tests where a new connection was created on each call instead of opening one from the connection pool.
2. Added services to test all six scenarios against MySql, PostgreSql, and Sql Server.
3. Disabled features that are not needed based on the test scenario specifications such as SOAP and CSV output formats.
4. Updated all third-party libraries to their current stable version.
5. Added some support scripts to Create and Populate the World and Fortune table if they do not exist when the application is started (for local development).
6. Added Swagger-UI feature for developers to explorer and test included services (for local development).
