Aligned client with ADO pipeline parameters.
Added function for creating and validating pipeline parameters instance to make explicit which parameters exist in ado pipeline.
Added feature of signing only provided images. This is needed for building in ADO as a building images and signing are two separate steps in a pipeline. These two steps are executed by different tools.
