FEATURE - Introduce global search

[cjbernal]

As a Knowledge Hub user,
I want to be able to search for content across all of the resources available in Knowledge Hub,
so that I do not have to enter my search terms across various tabs

Description

Currently Knowledge Hub has local search for all tabs. We can simplify our users' information search by allowing them to search across all of the materials they can access in KH. Similar implementations exist on the SAP homepage, which searches across SAP Community and Documentation: (https://www.sap.com/index.html); as well as SAP For Me, which searches SAP Community, documentation, and various other support materials (https://me.sap.com/home).

Technical Design

What modules need to be created or enhanced?
How would the functionality be exposed and how can it be consumed?

Acceptance Criteria

GivenWhenThen format (https://martinfowler.com/bliki/GivenWhenThen.html)

Given I have a Knowledge Hub open
