Allow the generate mojos (lint, doc, code gen, etc) to be able to read the specs from maven artefacts coordinates

[torrespro]

Instead of pointing to a single file as we do with inputSpec the idea is to create a new property in the configuration inputMavenArtifact to be able to download the artifact, unzip it and then generate code from it. Because our zips contain multiple yaml files and versions we need a param to specify the fileName.
