url_normalization_settings: Add APIs to get and update URL normalizat…

[tamas-jozsa]

Description

We want to start versioning URL normalization settings in HTTP Applications, so I'm adding these APIs.
The public API implements operations for getting and updating URL normalization settings.
Public API: https://api.cloudflare.com/#url-normalization-properties

Has your change been tested?

I created unit tests and I tested the APIs locally with my account.
