Adds E2E log test for RDS database interactions for Python

[georgeboc]

Issue description: This commit adds a logs test for the RDS database interactions for the Python programming language.

Description of changes: We are validating the logs returned against a template to the end-to-end test to ensure we detect any regressions, similarly as we are doing for Java in this PR. Please notice that this PR is building on top of the changes from this PR and this other PR.

This change was tested in this fork.

Ensure you've run the following tests on your changes and include the link below:
To do so, create a test.yml file with name: Test and workflow description to test your changes, then remove the file for your PR. Link your test run in your PR description. This process is a short term solution while we work on creating a staging environment for testing.

NOTE: TESTS RUNNING ON A SINGLE EKS CLUSTER CANNOT BE RUN IN PARALLEL. See the needs keyword to run tests in succession.

• Run Java EKS on e2e-playground in us-east-1 and eu-central-2
• Run Python EKS on e2e-playground in us-east-1 and eu-central-2
• Run metric limiter on EKS cluster e2e-playground in us-east-1 and eu-central-2
• Run EC2 tests in all regions
• Run K8s on a separate K8s cluster (check IAD test account for master node endpoints; these will change as we create and destroy clusters for OS patching)
