Add Kong image validation test after KO 2.0.0 GA

[randmonkey]

Problem Statement

In KIC, we have implemented a Kong image validation test that runs all e2e and integration tests to make sure that the rc images of Kong gateway releases are compatible with KIC. In KO we should also setup the workflow to check the compatibility with Kong gateway images.

Proposed Solution

• Add a Kong image Validation workflow to run required e2e/integration tests against the input Kong image to check the compatibility of the Kong image with KO functions
• Add an issue template to make gateway team able to create test requests to test a certain Kong image
• Implement some level of automatic to run such a test when a new Kong rc is uploaded/a test request issue is created

Additional Information

Acceptance Criteria

• There is a "validate Kong image" workflow to run tests against specified Kong gateway image to check the compatibility with KO
• An issue template for gateway team to create issue to track the tests
