Allow HTTP connections when no cassette

Usually, HTTP requests made when no cassette is inserted will result in an error.
You can set the allow_http_connections_when_no_cassette configuration option
to true to allow requests, if you do not want to use VCR for everything.

Background
Given
a file named "vcr_setup.rb" with:
if ARGV.include?('--with-server')
  start_sinatra_app(:port => 7777) do
    get('/') { "Hello" }
  end
end

require 'vcr'

VCR.configure do |c|
  c.allow_http_connections_when_no_cassette = true
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end
And
the directory "vcr/cassettes" does not exist
Scenarios

require 'vcr_setup.rb'

puts "Response: " + Net::HTTP.get_response('localhost', '/', 7777).body
When
I run ruby no_cassette.rb --with-server
Then
the output should contain "Response: Hello"
Cassettes record and replay as normal

require 'vcr_setup.rb'

VCR.use_cassette('localhost') do
  puts "Response: " + Net::HTTP.get_response('localhost', '/', 7777).body
end
When
I run ruby record_replay_cassette.rb --with-server
Then
the output should contain "Response: Hello"
