What did you implement:

Logging AWS SDK calls when SLS_DEBUG is activated.

Closes #5603

How did you implement it:

Configure the AWS.config.logger when SLS_DEBUG environment is activated.
In that case the AWS.config.logger will simply use the serverless.cli.log function to log AWS SDK calls.

Based on the official AWS documentation for logging :

How can we verify it:

In any serverless projects :

SLS_DEBUG=true serverless deploy

The console output should show the AWS SDK calls made by serverless :

Serverless: Invoke aws:deploy:deploy
