Cross: Update code repo CI pipelines for "bot-to-bot" integration test

[martinkearn]

AS A system engineer
I WANT the "bot-to-bot" integration test to be executed as part of the CI pipeline for each relevant code repo
SO THAT failures can be flagged automatically, and issues are not merged into the main branch

Use Docker Compose to execute the "bot-to-bot" integration test as part of the CI pipeline (i.e., gate to a pull request and merge to main) using local Docker containers as per https://github.com/buerokratt/Cross-functional-requirements/blob/main/docs/technical/integration-testing-strategy.md#docker-via-code-repository-ci-pipeline

Do this on the pipelines for the following code repos:

• https://github.com/buerokratt/Mock-Bot
• https://github.com/buerokratt/DMR
• https://github.com/buerokratt/CentOps

The mock classifier is not used in this test path so changes to the Mock Classifier will not affect the test outcome, therefore it is excluded

This will ensure that changes to any of these components are tested in terms of integration with other components.

Dependencies

• Cross: Design Integration Testing Strategy #13
• Cross: Implement "bot-to-bot" integration test #62
• Depends on Infrastructure: Update infrastructure CD pipelines for "classify a message" integration test POC-DMR.Infrastructure#42 being completed first as this will establish the surrounding project and code patterns for integration tests. Therefore, this task can be a "rinse and repeat" exercise.

Acceptance Criteria

• Add "bot-to-bot" integration test to the CI for Mock Bot
• Add "bot-to-bot" integration test to the CI for DMR
• Add "bot-to-bot" integration test to the CI for CentOps
