RFE:trigger deployment using GitHub actions

[bkaraoren]

Issue Summary

GitHub workflow that runs landscape.yml playbook on a GitHub runner which deploys everything from scratch.
With this CI/CD approach we can benefit that we do not need anything to run from our local workstations to build the environment. All the infrastructure can be build through a new commit / PR to the GitHub.

• add a variable in to the rhis-inventory, which enables to trigger
• add ansible vault password to the Github Runner variables as a secret
• add a workflow file that triggers ansible command line and using the inventory to execute landscape.yml
• add a condition that checks if the variable is set to true or false
