Add samples that require --net=host to examples repo

[bmpotter]

In 4.0 anax now supports this. There are 2 things that must be set:

• In the service definition deployment field: "network": "host"
• In the node policy properties: "openhorizon.allowPrivileged": true (See Node built-in properties )

Let's discuss which sample is the best illustration of using this.
