Output HTTP requests in logging

[paulturner-pg]

Is your feature request related to a problem? Please describe. When trying to debug issues with the provider, it would often be helpful to see the HTTP requests being made to the API and the responses received, as well as any non-sensitive headers involved.

Describe the solution you'd like I'd like to see requests in the standard Terraform output when the TF_LOG value is set to an appropriate level (e.g. Debug or Trace).

Describe alternatives you've considered I've tried routing requests through Fiddler, but our server only supports TLS 1.3, which is not supported by Fiddler. Using a proxy also introduces a new class of issues that has to be solved for all involved providers.
