Provide examples with file tree and deployment scripts

[gbryant-arm]

Requested feature
Provide examples with scripts capturing the program's specifications (file tree) and deploying the program in Veracruz:

• Script to deploy the program in the freestanding execution engine
• Script to deploy the program end-to-end on Linux
• Script to deploy the program end-to-end on Nitro
• The file tree can be described as a call to the policy generator and/or as a list of files

Motivation
Each program has a different file tree and interacts with different participants, which makes it tricky to deploy a program in Veracruz without encountering errors.
Besides the VOD example (https://github.com/veracruz-project/video-object-detection), there is no concrete example on how to deploy a simple program in Veracruz.
