Integrate deployment of Kai into Konveyor Operator

[jwmatthews]

We want to integrate Kai into Konveyor in an experimental feature gate manner.
Goals:

• Konveyor Operator is able to deploy Kai onto the cluster
• Deployment of Kai is disabled by default, we want a user to manually opt-in to deploying Kai
• Kai images may be overridden so someone opting to deploy Kai may specific the image path/tag for the kai image to use
• An exposed endpoint is available to reach the Kai service
• Authentication/Authorization requirements comply with Konveyor Hub expectations, i.e. same auth flows that work to with the Hub protect the Kai service
• The IDE plugin is able to specify and use the coordinates of the Kai endpoint Konveyor Hub is serving
• The IDE plugin is able to authenticate as expected with a protected Kai endpoint reusing credentials from Konveyor

As of August 2024 we plan to approach this work in a few milestones:

Milestone 1

1. Konveyor is able to deploy Kai in an unauthenticated manner and example/run_demo.py is able to run and talk to the remote Kai to test functionality is working, see ✨ Add support for deploying kai operator#374
2. We have an automated means to test that Konveyor + Kai integration is functional, see Konveyor Integration: Test Kai is functional deployed by Konveyor in an unauthenticated manner  #296

Milestone 2

1. VSCode IDE plugin is updated, see Handle connection to Kai server when it is deployed from Konveyor konveyor-ecosystem/kai-vscode-plugin#27

Milestone 3

1. Kai is deployed in an authenticated manner, conforming to Konveyor's auth workflow
2. A CLI based workflow is able to run with a specified token/header and proves functionality is working

Milestone 4

1. VSCode IDE plugin is updated to work with authentication values, likely implies need to work through an OAuth sign-in to go from username/pass to a token
