patman: Provide a way to intercept commands for testing
Add a test point for the command module. This allows tests to emulate the execution of commands. This provides more control (since we can make the fake 'commands' do whatever we like), makes it faster to write tests since we don't need to set up as much environment, and speeds up test execution.
