Issue 53723: ClassNotFoundException: JspServlet with additionalWebapp

[labkey-jeckels]

Rationale

We don't need JSPs for additional web apps.

Changes

• Manually register the default servlet and other config, but don't register the JSP servlet

• Manual Testing @labkey-adam
  • Use application.properties to configure an additional webapp
  • Create a simple JSP file in the additional webapp directory (a file with just <%= 5 + 3 %> works)
  • Ensure file is served up as simple text instead of rendering

I recommend reviewing org.apache.catalina.startup.Tomcat.initWebappDefaults() to ensure that I copied the right initialization code - not too much, not too little.

Reviewed against Tomcat sources and manually tested
