If I were to start making a pixel-art game with the Godot engine, what options do I have for removing the filtering or anti-aliasing from text?
I want to know how to remove the AA from rendered text in a label node.
Disabling anti-aliasing in DynamicFont isn't supported in Godot 3.0, but it's possible in 3.1 beta (which also makes it possible to tweak font hinting).
To do so, you need to create a DynamicFont as usual, load a TTF or OTF file into its Font Data property, edit the Font Data resource, set the desired anti-aliasing/hinting settings then save the font data resource as a
.tres file. (Otherwise, those settings won't be preserved when you exit the editor or launch the project.)
You can customize your image import setting in godot 3.0+. Here is how from the Godot documentation :
In the basic UI, when you select an image you can change tab to the import settings :

Here you can change several options to customize how your images are imported into Godot.
For pixel art, you can disable Filter and Mimaps for example.
PS : This solution works for Godot 3.0+, for Godot 2.1+ you can go to the corresponding documentation : Godot Docs 2.1+ : Managing image files. As you are stating you want to start a new game, it is recommended to use the latest (3.0+) version of Godot.
