Refactor Exporter in CLI

[chrisgacsal]

Description

Split logic implemented by Exporter into state.Manager and presenter.Presenter interfaces to separate responsibilities of managing state of the TargetScan (e.g. moving its status to InProgress) and how the scan results are presented (e.g. pulished to VMClarity API, written to console/file, etc.). These two interfaces are grouped together in the cli.CLI making the functionality provided both available via a single object.

State

The state.Manager has two implementations:

• state.VMClarity stores state updates to the VMClarity API
• state.Local is responsible to store/manage state locally

Presenter

The presenter.Presenter has the following implementations:

• presenter.ConsolePresenter allows printing scan results to the terminal/console
• presenter.FilePresenter saves scan results to files
• presenter.MultiPresenter allows combining multiple presenter.Presenter implementations
• presenter.VMClarityPresenter responsible for publishing scan results to the VMClarity API
