Add an integration test for system scope dependencies with war packaging

[m1stake]

Build a jar package would include mssql-jdbc.jar in the BOOT-INF/lib directory.
Build a war package would not include mssql-jdbc.jar in the WEB-INF/lib directory.

spring-boot version: 2.2.4.RELEASE

Thanks for your patience while we found time to look at this.

I believe that this is working as designed. In a war file, system scope dependencies are packaged in WEB-INF/lib-provided. This means that they are found in the war file and placed on the classpath when run using java -jar but hidden from the container in a traditional deployment. This allows the executable archive to be completely self-contained while allowing the container in a traditional deployment to provide system-scope dependencies.

I don't think we have an integration test that covers system scope dependencies with war packaging. We can use this issue to add one.
