/*

* About File:

	this is just a client that implements all the rest API from the FaaS, so each function it contains is an endpoint in the FaaS for deploying and similar

	refresh: updates the auth token
	validate: validates the auth token
	deployEnabled: checks if you're able to deploy
	listSubscriptions: gives you a list of the subscription available
	listSubscriptionsDeploys: gives you a list of the subscription being used in deploys
	inspect: gives you are deploys with it's endpoints
	upload: uploads a zip (package) into the faas
	deploy: deploys the previously uploaded zip into the faas
	deployDelete: deletes the deploy and the zip
	logs: retrieve the logs of a deploy by runner or deployment
	branchList: get the branches of a repository
	fileList: get files of a repository by branch
