[RoutingAutoBundle] Wrong documentation for the locale token provider

[greg0ire]

The locale_provider documentation claims it has three options:

• method
• slugify
• locale_format

It actually has no option at all.

Should the docs be modified, or will the provider end up with one these options ?

No, we simply need to remove it. The locale is provided directly by the PHPCR-ODM DocumentManager, in the form of de, fr, 'en' etc. I don't see any need for any options atm.

Ok, incoming PR.
