fix(cli): hotswapping appsync functions fails when API does not return function on the first page

[dpilch]

Issue # (if applicable)

aws-amplify/amplify-category-api#2307

Reason for this change

Hotswap for AppSync functions sometimes fails with Deployment failed: MissingRequiredParameter: Missing required key 'functionId' in params. This is because the SDK list function only retrieves the first page. In APIs where there are many functions it is possible for the hotswapped function to not be contained in the first page. This results in the previously mentioned error because the functionId is never retrieved.

Description of changes

List all AppSync functions for a given API by iterating through the pages with the nextToken. The change was modeled after a similar request here.

Description of how you validated changes

• Unit tests
• Integ tests
• Manual testing in app from Deployment failed: MissingRequiredParameter: Missing required key 'functionId' in params aws-amplify/amplify-category-api#2307

Hi! The cli integ test you wrote is not succeeding. Did you run this locally to ensure it worked? If not, the instructions for how to do so are here.

Specifically the failure is this:

const api = new appsync.GraphqlApi(this, "Api", {
--

ReferenceError: appsync is not defined

Looks like you need to add a line like this to the top of app.js. But please run the cli integ test on your own to ensure it does as its supposed to still!

Once that has been fixed i'll run it through the pipeline again.
