[Deployment Management] Add landing page redirect feature and implement in security solution

[sabarasaba]

Fixes #161000

Summary

The serverless-security solution will have their own management landing page that lives in a different URL as the management pages for oblt and search. To streamline access to all management pages through a single URL, we have implemented an API that allows the security solution to specify a different URL for redirection when required. This ensures a seamless user experience while navigating between various management interfaces.

As a placeholder for now I've set the redirect for the security landing page to:

management.setLandingPageRedirect('/app/security/manage');

How to test

• Boot up the security solution and make sure that going to http://localhost:5601/ekv/app/management will redirect you to http://localhost:5601/ekv/app/security/manage.
• Boot up any other solution and make sure that http://localhost:5601/ekv/app/management takes you to the managements default landing page.

Thanks for working on this @sabarasaba! Tested the endpoints locally in all serverless projects and the redirect feature works as expected. Code changes also look good to me! 🎉
