aws-smithy-http-tower: Lower log level of two info logs.

[vojtechkral]

Motivation and Context

aws-smithy-http-tower polutes our logs with info-level messages.

Description

Changed two info-level messages to debug level, it felt appropriate...

Testing

I wanted to run ./gradlew rust-runtime:cargoTest but I got the following error:

Task 'cargoTest' not found in project ':rust-runtime'.

Just so I understand this better, are you logging span open/close events? I don't think these emit normally.

No explicit configuration that I know of. We're seeing these in logs:
