Add methods to use the BTP CLI

[Dannick-debug]

Pull Request Description

Objective

This pull request introduces functions to facilitate the use of the BTP CLI. The key functionalities added include:

• Connecting to the BPI Cockpit (login/logout)
• Creating, retrieving, and deleting service instances
• Creating, retrieving, and deleting service bindings

Key Improvements

• CommandBuilder Implementation: A CommandBuilder has been developed to streamline script creation, ensuring efficient command handling.
• Execution Mechanisms: Two execution mechanisms have been introduced:
  • Synchronous Execution (Run): Enables concurrent task execution without blocking the main process.
  • Asynchronous Execution (RunSync): Incorporates a polling mechanism to verify the success of BTP actions at regular intervals.

Synchronous Execution

Currently, BTP actions do not support direct synchronous execution. To address this, a polling mechanism has been implemented to continuously check the status of actions, ensuring they are completed successfully.

Checklist

• Tests: Comprehensive tests have been conducted to ensure functionality and reliability.

Reviewed Authentication.go - will do the rest later.
I gave a little bit of feedback regarding the structure. It would be good to think about the loggedIn boolean again.

So this is a fist step, right? And then in another PR you will introduce the corresponding steps that consume this, or put an option into the cf deploy, and other cf steps, to use btp cli instead of cf cli?

Currently we provide the cf-cli with this docker image: https://github.com/SAP/devops-docker-cf-cli

Will you provide a docker image for the btp cli as well, or what is the plan?

Yes exactly it is the first step. In another PR we will then:

• introduce the consumption of these functions in the different steps.
• And also introduce an additional option in the different steps to choose between CF or BTP.

Thank you for bringing this up! Currently, our focus is on delivering the essential components in Golang for the BTP CLI. While we aren't providing a Docker image ourselves, team members who utilize these functions or steps will have the ability to create their own custom Docker environment if required.
