Implement install command for APT

[tomuben]

Background

Implement the APT install command, similar to the original PERL implementation.

<build_step>
	- Phase 1
		apt:
         - name: protobuf
            version: x.x.x
         - name: gcc
            version: x.x.x

We also need unit tests and integration tests. The integration test should install the packages in a Docker container.

Acceptance Criteria

• APT install command in Python
• Unit Tests
• Integration Tests
