Imitating the license header check from airshipctl

* script to check copyright
   Syntax: ./tools/check_copyright
* script to add license on missing files
   Syntax: ./tools/add_license.sh

* copied templates and scripts to check/add license header to
  file (go/yaml/yml/sh)

* Scripts can be customized for airshipui if required.
