io.vertx.core.Launcher class. Each command instance is created
by a CommandFactory.
Command implementation can retrieve argument and option using the Argument and Option annotations. Documentation / help is provided using the Summary (single sentence) and
Description annotations.
Commands follow a strict lifecycle. The setUp(ExecutionContext) method is called with an
execution context. It lets you validate the inputs and prepare the environment is needed. The
run() method is called immediately after setUp(ExecutionContext), and executes the
command. Finally, once the command has completed, the tearDown() method is called. In this method
you have the opportunity to cleanup.
