Use Case

We should investigate the need for https://www.npmjs.com/package/aws4 (aws4) as an optional peer dependency of the driver. When looking into the depths of the package it appears to have a small amount of functionality that we could inline in the driver as part of the AWS auth protocol logic. 

User Impact

• This could remove the need for users to have to install aws4 in order to get AWS auth working.
• It could be done in a feature version

Dependencies

• aws4

Unknowns

• Is it really a small bit of logic?
• Any concerns about maintainability?
  • Reporter note: I don't think any other drivers have a dependency for this, the logic here is in our common driver specification, it would need to be changed there for us to change the driver in anyway.

Acceptance Criteria

Implementation Requirements

• functional reqs, potential snafus to avoid, performance targets, etc

Testing Requirements

• unit test, spec test sync, etc

Documentation Requirements

• DOCSP ticket, API docs, etc

Follow Up Requirements

• Change ticket to compass changes needed if we proceed with removing the aws4 requirement for aws auth, so they can remove it from their packaging as well.
