Send running command a signal

You can send a running command a signal using
last_command_started#send_signal. This is only supported with
aruba.config.command_launcher = :spawn (default).

Background
Given
I use a fixture named "cli-app"
Scenarios
Existing executable
Given
an executable named "bin/cli" with:
#!/usr/bin/env bash

function hup {
  echo 'Exit...' >&2
  exit 0
}

trap hup HUP

while [ true ]; do sleep 1; done
And
a file named "spec/run_spec.rb" with:
require 'spec_helper'

RSpec.describe 'Run command', :type => :aruba, :exit_timeout => 1, :startup_wait_time => 5 do
  before(:each) { run('cli') }
  before(:each) { last_command_started.send_signal 'HUP' }
  it { expect(last_command_started).to have_output /Exit/ }
end
When
I run rspec
Then
the specs should all pass
