API Lambda to generate pre-signed URLs for uploading files

[briri]

New API function to support the generate of pre-signed URLs that COKI can use to send us match data files.

Initial part of #21.

Also fixed up some issues with the API function that pre-signs URLs to download DMP metadata files:

• Fixed name in package.json
• Removed unnecessary sam_build_deploy.rb script
• Fixed typo and remove unused imports
• Fixed broken tests

Just a couple of minor comments.

LGTM

Is there a way to run these unit tests locally? Whenever I try I get the error "Cannot find module '@aws-sdk/client-cloudformation'".

[briri]

yes, you need to be in the lambdas/api/put_dmps_uploads dir and run npm install first then npm run test that should install all of those dev dependencies.

I did that, but still see that error for some reason.

[briri]

Hmm. try going into the lambda/layers/dmptool/cloudformation directory and run npm install. Then go back to the lambda/api/put_dmps_uploads dir and run the tests again. They reference those lambda layers directly when you run locally so I wonder if the error is actually coming from the layer

Thanks @briri. That worked
