Add spec to confirm each app can have their own configuration
user
```ruby
require 'spec_helper'

RSpec.describe 'Multiple apps at once', :cannon_app do
  before(:each) do
    cannon_app.get('/info') do |request, response|

    app2 = Cannon::App.new(binding, port: 5032, ip_address: '127.0.0.1')
    app2.runtime.config.log_level = :error
    app2.get('/info') do |request, response|

    end

    app3 = Cannon::App.new(binding, port: 5033, ip_address: '127.0.0.1')
