3rd party modules updater for updatenotification (#3150)

Added my (modified) updater main core into updatenotification default
module

Missing: callback display in MM² (i will code it after)

new part of configuration added:

```
		updates: [
			// array of module update commands
			{
				// with embed npm script
				"MMM-Test": "npm run update"
			},
			{
				// with "complex" process
				"MMM-OtherSample": "rm -rf package-lock.json && git reset --hard && git pull && npm install"
			},
			{
				// with git pull && npm install
				"MMM-OtherSample2": "git pull && npm install"
			},
			{
				// with a simple git pull
				"MMM-OtherSample3": "git pull"
			}
		],
		updateTimeout: 2 * 60 * 1000, // max update duration
		updateAutorestart: false // autoRestart MM when update done ?
```

@khassel: i need your help
I don't use docker, maybe you can help me for this:
How can i check if MM² is running inside a docker ? (from MM² main core)
Actually, I check if we use pm2 or not.
I have to check if docker is used or not too
last time you tell me: "you can't use updater with docker", so I want to
check and deny any update if docker used
