WIP: [AMQ-9798] Refactored Web Console and removed dependency on Spring-MVC.

[sergio-d-lemos]

This PR removes the dependency on Spring MVC and does some clean ups in the Web Console. Apologize for the long PR.

• spring-context is used to inject beams into the context
• Created the ActionServlet which plays the role of the DispatcherServlet (from spring-webmvc)
• Removed the applicationContext because I could not find any JSP page using it
• Moved CSRF validation to its own Filter
• Minor clean ups here and there

I tested each page using Chrome and did some sanity tests using Firefox. I was unable to test running the console on an OSGI container, but I can test if we think is necessary.

Can we also write some tests for the change?

Great initiative!

Yes, if we don't need any major change to the PR I will include some unit tests. At least for the classes I've added

That's a nice PR, thanks !

At first glance, it looks good to me. I don't think we would need additional tests compared to what we have today.

However, I think the Karaf features have to be updated to cleanup the dependency there as well. I can help on this front.

Let me do a complete review.

Thanks JB, I'm not very familiar with Karaf, appreciate any help on this front, I can also take a look.
