chore: Add test name to request logging and remove default region from pytest.ini

[qingchm]

Issue #, if available:
N.A.

Description of changes:
In the integration test logging, when tests are running in parallel, the position of the logging messages does not follow the exact test it belongs to. Therefore a header is added to indicate the test case each request belongs to.

Description of how you validated changes:
Ran locally to see the logs:
REQUEST LOG [test_cors_1_combination_api_with_cors_openapi] | Time: 2022-09-22 22:28:08,487 Request made to https://* | Status: 200 | Headers: {*}

Checklist:

• Add/update unit tests using:
  • Correct values
  • Bad/wrong values (None, empty, wrong type, length, etc.)
  • Intrinsic Functions
• Add/update integration tests
• make pr passes
• Update documentation
• Verify transformed template deploys and application functions as expected
• Do these changes include any template validations?
  • Did the newly validated properties support intrinsics prior to adding the validations? (If unsure, please review Intrinsic Functions before proceeding).
    • Does the pull request ensure that intrinsics remain functional with the new validations?

Examples?

Please reach out in the comments, if you want to add an example. Examples will be
added to sam init through https://github.com/awslabs/aws-sam-cli-app-templates/
