[App Service] Add more Java SE deployment tests of non-Spring Boot apps

[brunoborges]

The plugin works mostly well for Spring projects. For non-Spring, it is unclear whether it will work, given that other frameworks may have different set ups and outputs.

Frameworks to consider:

• Micronaut
• MicroProfile (Payara, Thorntail, and Helidion)
• Quarkus
• Dropwizard
• SparkJava
• Ratpack
• Undertow

This should give good coverage and also validate whether Azure App Service itself is working accordingly.
