Work still progressing on this, but interested in early feedback.

Hi @stephenbawks, thank you so much for your effort in creating this!

I wanted to let you know that in order to add a new feature, we have a specific process that requires opening a feature request (possibly with a Request for Comments or RFC)[https://github.com/awslabs/aws-lambda-powertools-python/issues/new?assignees=&labels=RFC%2Ctriage&projects=&template=rfc.yml&title=RFC%3A+TITLE] before we consider implementing a new utility.

Additionally, to ensure better visibility, it would be really helpful if you could answer the following questions:

1/ What are the differences or gaps between SigV4Auth and the well-tested utility available at https://github.com/davidmuller/aws-requests-auth?
2/ Can we find this utility in the Lambda Runtime's boto version (1.29.90)?
3/ Is it possible to make the utility name more general, allowing for future growth? For example, JWT is another popular requirement.

I kindly request you to open a Feature Request/RFC with these answers, so that we can gather feedback on the proposed utility! Once again, I sincerely appreciate your valuable time :)

Folks - what's the latest here?

Sorry for the delay but I have gone ahead and created the RFC.

[heitorlessa]

Thanks a lot @stephenbawks !! Gonna make comments in the RFC shortly

[heitorlessa]

Quick heads up it's missing details and CI checks still. I'll put this for August

[sthulb]

@heitorlessa / @stephenbawks Coming back to this PR, is there anything else needed before we review and merge?

Leandro shared that docs and UX need a final pass -- I'm scheduling this for the next iteration cycle starting on Monday (Feb 12th-22nd) to make the cut for that release cycle.

@heitorlessa @sthulb

Let's do it. I have been waiting to complete my trifecta of PRs so that I can do more with VPC Lattice so I will do whatever we need here. I saw your comment about a RFC so I will get that going.

I did create an RFC a while back but I am assuming it needs to be updated.

#2713

@stephenbawks Thanks for commenting. Initially, I'll say this is missing tests for sure (unit/func/e2e) before we can review this properly.

After a deeper look into the PR & RFC, we're missing a few things like docs and tests.

I'm wondering if we care about the JWT side of this PR – perhaps this should be split into a different RFC so we can decide it's something we need. There's definitely a need for SigV4(a) signing util since that would be a nice convenience utility.

I am getting back into the swing of things here. I would like to get this PR over the finish line, its been a while in the making.

I think we could certainly split it into two different PRs. Just wondering if there is any more thought on that from anyone else. I feel like most of the work is done for adding JWT/client credentials but I am interested in feedback.
