CASSANDRASC-46: Migrate minikube to testcontainers for integration tests

The existing Cassandra Sidecar integration testing suite uses Minikube to provision a
Cassandra service and it performs tests against the running database. This database runs
on Minikube.

A new alternative is to use [testcontainers](https://www.testcontainers.org), which requires
Docker to run tests. The concept is similar, but the benefit is that *testcontainers* is
well integrated into the java ecosystem and it works well with junit5. By replacing Minikube
with `testcontainers` we can simplify the setup process and reduce the complexity for running
integration tests.

Additionally, `testcontainers` is supported as part of the testing infrastructure inside
[CircleCI](https://www.testcontainers.org/supported_docker_environment/continuous_integration/circle_ci/).
Currently, our Minikube tests are broken both locally and in CircleCI. Moving to `testcontainers`
would also unblock us for further development.

Minor fix when running testcontainers

Apache Cassandra Sidecar [WIP]

This is a Sidecar for the highly scalable Apache Cassandra database. For more information, see the Apache Cassandra web site and CIP-1.

This is project is still WIP.

Requirements

  1. Java >= 1.8 (OpenJDK or Oracle), or Java 11
  2. Apache Cassandra 4.0. We depend on virtual tables which is a 4.0 only feature.
  3. Docker for running integration tests.

Getting started: Running The Sidecar

After you clone the git repo, you can use the gradle wrapper to build and run the project. Make sure you have Apache Cassandra running on the host & port specified in conf/sidecar.yaml.

$ ./gradlew run

Configuring Cassandra Instance

While setting up cassandra instance, make sure the data directories of cassandra are in the path stored in sidecar.yaml file, else modify data directories path to point to the correct directories for stream APIs to work.

Testing

We rely on docker containers for integration tests.

The only requirement is to install and run Docker on your test machine.

CircleCI Testing

You will need to use the “Add Projects” function of CircleCI to set up CircleCI on your fork. When promoted to create a branch, do not replace the CircleCI config, choose the option to do it manually. CircleCI will pick up the in project configuration.
