Add support for Spring Boot 3.0 once Open Liberty supports it

[cherylking]

Open Liberty is adding support for Spring Boot 3.0 with this epic. Some plugin code will need to be modified in order to support it, and a new test case should be added. Similar updates will be needed in Liberty Gradle Plugin as well.

Looks like Open Liberty 23.0.0.9 will include Spring Boot 3.0 and has an eGA of 9/19.

@hlhoots @cbridgha Is someone from your team looking at the changes needed in the Liberty Maven and Gradle plugins for support of Spring Boot 3.0? The original support was added by Anjum Fatima. I am somewhat familiar with the code, but would need definite pointers on the changes needed.

Its not clear anything specific to SB 3 needs to happen - @cherylking Can you find the original PR from @anjumfatima90 ? Maybe at most you guys need to add a testcase?

I know changes are needed, as there is logic specific to 1.x vs 2.x. I will find the original PR and link it.

Here are a couple of examples in ci.gradle that would need modifying. I would expect something similar in ci.maven, but have not tracked it down yet. I cannot link the original PRs because that code was added before we migrated our repos to OpenLiberty in public Github.

I don't know if there are any fundamental differences that need to be accounted for between 2.x and 3.x.

Open issue in ci.gradle related to SB 3.0 support.

[cherylking]

There are 4 classes and 6 different methods that check for version 1.x versus 2.x in the ci.gradle code. I found none in ci.maven code.

While adding a test case for SpringBoot 3.0, I ran into a NoClassDefFoundError when our plugin code calls the springBootUtility. That problem is being tracked in this OL issue.
