Maintenance: append user agent to AWS SDK clients

[dreamorosi]

Summary

The AWS SDK v3 allows to add user agent headers to the requests made using its clients via its middleware stack.

Why is this needed?

So that AWS can attribute requests made to its API when using Powertools.

Which area does this relate to?

Governance

Solution

Expose a shared function that takes a client and adds a middleware to it that will attach Powertools-related user agents to the request. This shared function can then be used by other Powertools utilities that make requests to AWS APIs.

Acknowledgment

• This request meets Powertools for AWS Lambda (TypeScript) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and .NET
