Matching on Headers

Use the :headers request matcher to match requests on the request headers.

Background
Given
a previously recorded cassette file "cassettes/example.yml" with: 
--- 
- !ruby/struct:VCR::HTTPInteraction 
  request: !ruby/struct:VCR::Request 
    method: :post
    uri: http://example.net:80/some/long/path
    body: 
    headers: 
      x-user-id: 
      - "1"
  response: !ruby/struct:VCR::Response 
    status: !ruby/struct:VCR::ResponseStatus 
      code: 200
      message: OK
    headers: 
      content-length: 
      - "15"
    body: user 1 response
    http_version: "1.1"
- !ruby/struct:VCR::HTTPInteraction 
  request: !ruby/struct:VCR::Request 
    method: :post
    uri: http://example.net:80/some/long/path
    body: 
    headers: 
      x-user-id: 
      - "2"
  response: !ruby/struct:VCR::Response 
    status: !ruby/struct:VCR::ResponseStatus 
      code: 200
      message: OK
    headers: 
      content-length: 
      - "15"
    body: user 2 response
    http_version: "1.1"
Scenarios
Replay interaction that matches the headers
And
a file named "header_matching.rb" with: 
include_http_adapter_for("http_lib")

require 'vcr'

VCR.configure do |c|
  configuration
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example', :match_requests_on => [:headers]) do
  puts "Response for user 2: " + response_body_for(:get, "http://example.com/", nil, 'X-User-Id' => '2')
end

VCR.use_cassette('example', :match_requests_on => [:headers]) do
  puts "Response for user 1: " + response_body_for(:get, "http://example.com/", nil, 'X-User-Id' => '1')
end
When
I run ruby header_matching.rb
Then
it should pass with: 
Response for user 2: user 2 response
Response for user 1: user 1 response
Examples:
configuration http_lib
c.hook_into :fakeweb net/http
c.hook_into :webmock net/http
c.hook_into :webmock httpclient
c.hook_into :webmock curb
c.hook_into :webmock patron
c.hook_into :webmock em-http-request
c.hook_into :webmock typhoeus
c.hook_into :typhoeus typhoeus
c.hook_into :excon excon
