SAVON 3 Use of Nori should include configurable nori options

[tjarratt]

Migrated from savonrb/savon#543

---

Though the change log current says that your are not using Nori, you are still using it
in the response. Unfortunately for me one of the cool elements of using the response header, in the request headers (for soap services that return a changing token in the Securtiy header) is not working since you default to snake_case on the symobls returned.

Can we get :

  def self.configure
      yield self
    end


in the savon.rb file  so we can set some options:

mattr_accessor :nori_options
@@nori_options =     nori_options = {
    strip_namespaces: true,
    convert_tags_to: lambda { |tag| tag.snakecase.to_sym }
  }

I'll be happy to fork it, but I'm terrible at writing rspec.

Or if this is undesirable (because you are referencing :envelope, and :body direectly in the response Object)
is there some otherway you recommend getting header elements into camelcase?

For now, I've monkeypatched Nori to camelcase anything inside [:envelope][:header] in my app using :symbol_name.to_s.camelcase.to_sym
