Concurrency 3.1: Expand app-defined concurrent resources with Qualifiers and Virtual

[KyleAure]

User Story:
"As a user of Liberty, I want to be able to use the qualifiers and virtual config options on managed executors and managed thread factories within my application."

This is an expansion of the work done during Concurrency 3.0 under issue #18669

Scope:

• Need to update liberty to parse and merge this configuration from web.xml, application.xml, and from application annotations.
• From what I've seen ejb-jar.xml schema is no longer being updated to include any resource additions/changes that are going into Jakarta EE 10/11.

Testing:

• Verify model via unit tests added to com.ibm.ws.javaee.ddmodel
• Integration testing will be added as virtual threads and CDI injection of concurrent resource features are implemented, this is a prerequisite to that work.

Questions:

• When will Jakarta EE 11 schema (xsd) be released and how is it integrated into Liberty?
• Is there anything we need to do to make sure these new config options are added to the XSD?
  • Looks like a pull request will need to be opened here: https://github.com/jakartaee/jakartaee-schemas
