HTTP mocking

Some scenario types might require mocking third party services. Mock server component
can be used for that. It is based on simple http mock server called smocker.

Using

Simple usage example:

Component::Gitlab.perform do |gitlab|
  gitlab.network = 'test'
  gitlab.instance do
    Component::MockServer.perform do |mock|
      mock.network = gitlab.network
      mock.instance do
        Component::Specs.perform do
          ...
        end
      end
    end
  end
end

Mock server will be accessible from within gitlab or qa test container via http://smocker.test url and admin interface will be
accessible via http://smocker.test:8081. Refer to Getting Started guide on
how to use the server and define mocked requests and responses.
