Goal:

• To make sure the worker receives a payload that nobody hasn't tampered with, the bash script will be signed by trusted employees and the worker needs to verify the signature.

Acceptance Criteria:

• The worker verifies that nobody has tampered with the contents of the bash script
• The worker shall receive the data in a playbook-like format and use insights-client to verify the signature
• Prepend all variables located under /vars/content_vars with RHC_WORKER_* and set them in the unix environment
• Include a go-yaml library in the project to process the incoming yaml.
