Import failed - version differences

We should try to avoid enable users import projects that has an old format (before project oriented).

This probably will demand to create a temp repo, check if it has a pom file in the root. If pom file exists, check the content looking for:

• kie-maven-plugin usage (if not used, fail)
• some mandatory kie dependencies (if not, fail)
• check if it defines modules, if it does... fail
