There was a problem hiding this comment.
nit: use momento_functions_wit::host::momento::functions::token::TokenError so you can tidy this block's line noise. There aren't any other TokenError names that would be confusing, and you still stay below 100 lines I think :-p

Reworked from #22 to instead generate a JSON string that will be interpolated by the host to support genereating disposable tokens from functions.
Original PR description:
Momento currently has examples on how to make a token vending machine for temporary, scoped Momento tokens. But those examples are typically based around some form of a cloud deployment, such as AWS using API Gateway backed by a Lambda function and aren't protected by auth.
This PR ports over the functionality for vending temporary tokens using Momento Functions instead. This gives you a powerful, fast way to generate specific tokens for your customers without having to manage CloudFormation stacks, racking up AWS bills, etc. as well as having the confidence in knowing your function's endpoint is secure.
