Develop new test case for AWS VPC integration with multiple FlowLog

[nico-stefani]

Description

During the Alpha1 phase of 4.6.0, we found an error wazuh/wazuh#18901 that wasn't caught by the integration tests of the AWS module wazuh/wazuh#18879 (comment).
So, is needed to design and develop a new test case to cover this behavior.

Configurations

Proposed test cases

As a reference the original test cases were defined in #3336

• VPC Flow integration works properly with only_logs_after option and multiple FlowLog configured.

Update

• I was looking at how the tests are divided, how to develop it and getting started
• I start to create the test_case script on the issue

Update

• I finished developing the test in test_only_logs_after, I have been developing the cases inside only_logs_after_test_module, I still need to run it and test its operation.

Update

• I was modifying the new related multiple FlowLog test and adding new test_case in only_logs_after_test_modle
