one to authenticate and another one to create\delete webhooks

(currently I'm sending the githubToken to the client and it sends it back when creating a webhook. need to keep only the firebaseToken on the client side

currently, written as a comment since I need to also import the **account key** in some fancy way

private config file should make it easier to save configuration to disk (DB url, etc)

this will handle all configurations (also will save the configuration you add as argv if you add --savePrivate)

I still need to make this simpler, but it's already simpler than the previous one :-)

later, should replace this with a function that does this internally

I want to change the functions inside userService to not use req and res so that it will be simpler to test.

after that change, I'll change this to test the actual file and not the function I mocked a few lines before :-)
