Base Attribute Middleware and Router update

[regisoc]

Brief summary of changes

This PR adds:

• a first middleware RequestAttributeBuilder: placed at the top of the middleware chain to initialize some essential attributes when receiving a request i.e. loris, user, baseurl. This helps extract base attribute from any received request further down the chain or even after.
• a second middleware RedirectControl: to control redirect query parameter if set. It will control if the redirect URL query parameter is targeting the current host from the server.
• refactors a bit the base router to get attributes from the change in middlewares.

I like this PR!

Random thought out of scope for this PR, but would it be desirable to have a custom LorisRequest (or LorisRequestInterface) type that extends ServerRequestInterface with typed attributes/getters for loris and user such that these important objects can be type checked / have auto-complete / are more discoverable 🤔.

Or alternatively, some functions getLoris($request) or getUser($request) that use the standard ServerRequestInterface 🤔.

Yes. This is a first PR to allow all parameters to be accessible down the pipe.
We can add and control much more down the line.
