Hadoop Validator for projects not using Hadoop DSL #124
Description
Currently the Hadoop Validator can only validate pig scripts of projects using Hadoop DSL. We should support validation of any general pig script that can be run on gateway by taking appropriate parameters.
Also it's good to include validation as a part of build for all hadoop projects with Pig scripts. We might want an optional parameter to disregard it's validation in build by running ligradle build -x pig Validate
