Update the hook order because the functions need the .zip file in their resource
definition. Furthermore the zipping process / writing it to disc was optimized.
The ".serverless" directory is also added to the "default exclude array" so that it's not
considered during packaging.
The awsDeploy plugin now uses different lifecycles to split the tasks up and
introduce a way for 3rd party plugin developers to hook into those lifecycle to e.g.
add resources before everything is deployed.
