AWS_NODEJS_CONNECTION_REUSE_ENABLED doesn't exist in V3

[perpil]

Describe the issue

I'm researching an issue with the AWS_NODEJS_CONNECTION_REUSE_ENABLED env variable mentioned here. It appears to exist in V2 of the JavaScript SDK, but doesn't exist in the V3 sdk. When I grep my node_modules for that string, it doesn't exist when I use V3 clients (but does appear in the cdk).

❯ find . -type f | xargs grep -l AWS_NODEJS_CONNECTION_REUSE_ENABLED
./aws-cdk-lib/aws-lambda-nodejs/lib/function.d.ts
./aws-cdk-lib/aws-lambda-nodejs/lib/function.js
./aws-cdk/lib/index.js
./aws-cdk/lib/index.js.map
./aws-cdk/lib/api/aws-auth/sdk-provider.js

The only way of turning connection reuse off is to set the keepAlive: false in the Agent in V3. Can you confirm that AWS_NODEJS_CONNECTION_REUSE_ENABLED doesn't actually do anything in V3 and remove it from the documentation if so?

Hi @perpil,

Thanks for your report. I can confirm that AWS_NODEJS_CONNECTION_REUSE_ENABLED does not exist in v3. We will remove this from the docs.

Good find.
Thanks again,
