Add some real sample apps

[sevensolutions]

The sample-job isn't really practical because it just hosts the default IIS start page from an absolute path.
In a real world you would eg. download your own app via nomad's artifact block.
Therefore I'll add some simple sample apps to the repo.
Maybe a simple static page and a simple ASP.Net App.

I've now added a second example job for a simple ASP.Net app which can also be used to inspect environment variables and test permissions.
