Repackage hooks support as a codemod

[kevinbarabash]

I'd like to be able to use the hooks support to upgrade a large number of simple components in my codebase.

Hey @kevinbarabash. I have a plan to extract the refactoring engine into a separate package, to allow it to be ported to other IDEs. This will allow You to use the whole engine without the IDE and simply provide inputs and outputs from the medium of Your choice. The work is already underway, but will take some time to complete. Meanwhile, you can find the refactoring You've mentioned here: https://github.com/wix/vscode-glean/blob/master/src/modules/stateful-to-stateless.ts

@borislit Can vscode convert all files in some directory? (i mean use vscode formatting instead of use cli for refactor). I wanna convert all files instead "open one file, convert it, repeat", but i don't know vscode features
