[WIP] feat: nginx-aws-signature lib submodule

[shawnhankim]

Background:

• As a SWE, I want to reuse nginx-aws-signature lib for not only S3 gateway but also other AWS services gateway such as Lambda gateway.

Description:

• Move aws signature lib into the repo nginx-aws-signature
• Sparse checkout the submodule in the nginx-s3-gateway.
• Changed the name of environment variables of AWS credentials for common AWS signature lib.

Rather than a submodule, would you consider distributing the aws signature library via npm?

Thanks @dekobon for your comment. It is a great point! Sure, I will consider it. In the meantime, I would appreciate it if you could review #126 as the first step when you get a chance.

@shawnhankim, Did you get a chance to experiment with distributing via NPM of this nginx-aws-signature lib? I'm considering NPM for my use case and would like to learn/see what experience for NJS modules looks like.

@ivanitskiy , Thanks for the question.

• I just registered the NPM package in the https://www.npmjs.com/package/nginx-aws-signature via my personal account.
• We additionally need the following action items.
  • Support multiple JS files in the NPM package
  • Build and register the NPM package with version bump via public account in the CI/CD pipeline
  • Integrate NPM package with NGINX S3 Gateway by referencing https://nginx.org/en/docs/njs/node_modules.html
  • Integrate NPM package with NGINX Lambda Gateway to see if the nginx-aws-signature is compatible for several Amazon services
  • Update README.md in the following repos:
    • NGINX AWS Signature Library
    • NGINX S3 Gateway
    • NGINX Lambda Gateway
• As you and @dekobon might know, I am currently focusing on other urgent project, and there would be some delay for this. So I have invited you as a maintainer in the repo of NGINX AWS Signature Library in case you are interested in enhancing and registering it to the NPM package site.
