Tez UI 2: Release audit is failing

Seven files are having license issue

tez-ui2/src/main/webapp/config/configs.env
tez-ui2/src/main/webapp/testem.json
tez-ui2/src/main/webapp/public/crossdomain.xml
tez-ui2/src/main/webapp/public/robots.txt
tez-ui2/src/main/webapp/tests/.jshintrc
tez-ui2/src/main/webapp/blueprints/.jshintrc
tez-ui2/src/main/webapp/app/templates/dag/graphical.hbs

• testem.json, .jshintrc, tmp directory and image assets need to be added into apache-rat-plugin excludes list
• License must be added to configs.env & graphical.hbs
• crossdomain.xml & robots.txt was created by ember project generator, but can be removed as we don't use them currently
