Orbit properties are not discoverable

🐞 Problem

None of the delegated properties of Orbit appear in the documentation or the autocomplete, including all the classical elements.

🎯 Goal

Clearly inform the user what are the possible operations with Orbit objects without having them figure out thanks to the notebooks, or investigating what a _BaseState object is.

💡 Possible solutions

• Perhaps we should stop using magic delegation to a property, as suggested in #370.
• Another option is to load all these properties on class creation to allow Sphinx to detect them while creating the docs

It’s true that I’m missing some methods there, but we are not using introspection there so it has to be another issue.

There might be a way to fix this issue without changing the design though, but I am not aware of it.
