* added license templates for go, bash & yaml in tools dir
* added a script that will add license information for all
missing files. Type: go, yaml, yml, sh
* skip adding license for all files within testdata
* Syntax:
> ./tools/add_license.sh
* Skip license for manifests folder
* Added one extra line after licene for yaml files
* Added License after Hashbang for bash.
* Add an extra line after hashbang and before license
* Updated the go template to use multiline comments
New Files:
1. tools/add_license.sh
2. tools/license_go.txt
3. tools/license_yaml.txt
4. tools/license_bash.txt
