Title: [DependencyInjection] Add normalization to tag options

Currently, when using tags in XML, the options aren't normalized. This means that the following code is wrong:

It should be `manager_name` to remove errors, but that's not following the XML rules. The solution is to use the same normalization as the configuration: replacing - with _.

To be BC, both options (with and without normalization) are kept
