CLOUDSTACK-1233: Fixed veewee config file legal documentation

The veewee configuration files used for the devcloud base-box build, as
well as the newly introduced files used to create a system vm, were
inappropriately identified as ASLv2 licensed and copyrighted by the ASF.

The fixes:
- The ASF headers stripped to match the source.
- The files are now excluded from RAT checks in the root pom.
- The tools/whisker/descriptor.xml file updated
- The root LICENSE and NOTICE were re-generated

Changes in the Apache Whisker templates for LICENSE and NOTICE files
caused a good bit of whitespace oddness in this commit for those 2
files.
