Allow AsyncAPI mocking and contract-testing support

[lbroudoux]

Reason/Context

As of today (version 0.1.4 of this library) we just support essential features of Microcks provided by the main Microcks container. The list of supported features is the following:

• Mocking of REST APIs using different kinds of artifacts,
• Contract-testing of REST APIs using OPEN_API_SCHEMA runner/strategy,
• Mocking and contract-testing of SOAP WebServices,
• Mocking and contract-testing of GraphQL APIs,
• Mocking and contract-testing of gRPC APIs.

Asynchronous API mocking and ASYNC_API_SCHEMA contract-testing strategy are not supported at the moment as it would require an additional microcks-async-minion container as well as a Kafka broker to ensure communication with the main container.

Description

We'd like to extend the notion of MicrocksContainersEnsemblewe described in #24 to also allow the usage of Microcks asynchronous features.

Implementation ideas

Ideally, we should be able to manage 2 different modes:

• the one we're providing a Kafka broker because the user doesn't care (typically, we'll use a RedPanda testcontainer here)
• the one we're reusing a Kafka broker that the user has initialized. In that case, we may want/need to reuse or share the same docker network and also have loose-coupling just reusing a broker bootstrap URL to connect everything

Now that we have microcks/microcks#1020, we can tackle this one more lightweight and efficiently!
