Migration: https://issues.apache.org/jira/browse/HOP-3193

Beginning with projects and environments it becomes more important to keep an inventory of variables used in a project.  Current best practices are that environments provide specific values for variables that are used in a project.  A hop project contains the real variables used for connections, file paths, and other parameters.

What we are trying to solve is making it easy for a user to put a project into play by quickly identifying what variables require assignment.

When people download a Hop project, even the samples that come with Hop, there is no included "Environment" file with the value definitions that plug in for a project.  A user is left to go through all the facets of a project to look for variables that need a value.
