table.* APIs only support AppSync's contract

[thantos]

There are two sets of dynamo integrations (where * are all of the dynamo query and mutate APIs):

1. table.*
2. $AWS.DynamoDB.*

Currently table.* uses a contract specific to AppSync:

table.query returns { items: [...], nextToken: "", scanCount: number }

But nextToken is a concept that appsync made up, it isn't something we easily recreate in functionless.

• Could recreate by encrypting and encoding the token, but this assumes that appsync is the only integration that has a unique contract and that all other services must follow them
• Could use the dynamo contract, but app sync cannot do that as the LastEvaluatedKey is obfuscated in the next token and not returned.

Options:

1. All integrations with dynamo tables conform to appsync's contract table.query
2. Breaking change that creates a set of table APIs for only app sync, leaving table.* for services that use dynamo's contract (ex: step functions, lambda)
