deprecate Onceler.configure

[jenseng]

Instead of doing:

RSpec.configure do |config|
  config.include Onceler::BasicHelpers
end

Onceler.configure do |config|
  config.before :record do
    # reset some caching to ensure all recordings get a blank slate
  end
end

You should be able to do:

RSpec.configure do |config|
  config.include Onceler::BasicHelpers

  config.before :record do
    # reset some caching to ensure all recordings get a blank slate
  end
end
