UT Tools

Continuous integration, continuous delivery and automation scrips to be used
within package.json scripts section. Some updates.

Starting with ut-tools version 7, it needs to be installed as a global package,
instead of adding it in devDependencies, which will only slow down
npm install for each developer and the Jenkins builds.

To enable VSCode linter to use the same rules as ut-tools, add these settings
in the appropriate place (user or workspace settings ctrl+, ):

``json
{
"eslint.options": {
"overrideConfigFile": "/enter the installation path here/ut-tools/eslint/.eslintrc.js"
},
"eslint.nodePath": "/enter the installation path here/ut-tools/node_modules"
}
``
