Readme/official documentation is missing client ID to be whitelisted to use clasp

[chrisirhc]

Is there anyway to get the App ID added to some kind of official Google approved documentation? Many organizations have super tight security requirements and can't/won't authorize random App IDs they see in source code files. They need to see something official saying that is the App ID so there is accountability. Something that shows 1072944905499-vm2v2i5dvn0a0d2o4ca36i1vge8cvbn0.apps.googleusercontent.com belongs to Google for clasp and that Google's privacy policy applies.

Updated readme with instructions on allow-listing or setting up an internal-only project for clasp.
