Changes the API internals to use normal Laravel binding which automatically supports nested-models and can determine their relationships. This removes a lot of confusingly complex internal logic and replaces it with standard Laravel code.
This also removes a deprecated "getModel" method and fully replaces it with a "parameter" method that does stricter type-checking.
Versions of Pterodactyl prior to 1.6.3 used a different throttle pathway for
requests. That pathway found the current request user before continuing on to
other in-app middleware, thus the user was available downstream.
Changes introduced in 1.6.3 changed the throttler logic, therefore removing this
step. As a result, the client API could not always get the currently authenticated
user when cookies were used (aka, requests from the Panel UI, and not API directly).
This change corrects the logic to get the session setup correctly before falling
through to authenticating as a user using the API key. If a cookie is present and a
user is found as a result that session will be used. If an API key is provided it is
ignored when a cookie is also present.
In order to keep the API stateless any session created for an API request stemming
from an API key will have the associated session deleted at the end of the request,
and the 'Set-Cookies' header will be stripped from the response.
Previously, a single key was used to access the API, this has not changed in terms of what the user sees. However, API keys now use an identifier and token internally. The identifier is the first 16 characters of the key, and the token is the remaining 32. The token is stored encrypted at rest in the database and the identifier is used by the API middleware to grab that record and make a timing attack safe comparison.
