Orchestrator - Single Action NetApps visibility

[Artonus]

Description

The aim of this feature is to enable communication between multiple NetApps. This scenario makes a few assumptions:

• The NetApps that can communicate with each other are placed in a single Action during planning
• All NetApps will know about each other's existence
• The addresses of the other NetApps are exposed through Environment Variables
• The environment variable is named exactly as the NetApp it exposes. With exception that instead of -, there are _ and name is uppercase

Fixes: #161

Type of change

• New feature (non-breaking change which adds functionality)
• This change requires a documentation update

What has been changed?

2. Feature: NetApps within the same action are exposed to each other through environment variables
3. Doc: documentation of the process

How Has This Been Tested?

• Unit tests confirming that the environment variables are assigned
