Return 400 status for invalid URI

[pmd1nh]

Describe the bug
com.ibm.ws.webcontainer.set400SCOnTooManyParentDirs="true" does not have an effect. Default value is false.
Also need a shortname for it in Liberty

Steps to Reproduce
When a request URI has too many traverse path characters (i.e /contextRoot/../../../../../index.jsp ), the request is rejected with a 500 status code. It should have rejected with a 400 (Bad Request).

Expected behavior
After set com.ibm.ws.webcontainer.set400SCOnTooManyParentDirs="true", request with too many path traversal character (i.e /../../ ) should be returned with 400 Bad Request.

Diagnostic information:

• OpenLiberty Version: [23.0.0.7 and below]
• Affected feature(s) [servlet-5.0 and below]

Additional context
Note: Servlet-6.0+ returns 400 Bad Request without any additional property.
