Apple Silicon (M1) ARM64 Compatibility

[rieckpil]

The default course application infrastructure doesn't start on a recent Mac with the M1 (ARM64) processor.

The main reason is the missing ARM support for the following Docker images:

• sqs-alpine (can be replaced withsoftwaremill/elasticmq-native or LocalStack >= 0.13.0) ❌
• selenium/standalone-chromeand selenium/standalone-firefox (used for web tests): ARM64 support discussion is currently ongoing, first multi-arch images are available: https://hub.docker.com/u/seleniarm and can be used with DockerImageName.parse("seleniarm/standalone-chromium:latest").asCompatibleSubstituteFor("selenium/standalone-chrome")

Working images:

• LocalStack (SQS) since version 0.13.0 ✅
• PostgreSQL ✅
• Keycloak (using a community build: [richardjkendall/keycloak-arm](https://github.com/richardjkendall/keycloak-arm or Keycloak >= 17) or mihaibob/keycloak) ✅
• Selenium WebDriver Container (when using the seleniarm counterparts) ✅

UPDATE 🥳: A small tweak is required to get the application and tests running on ARM64 👇🏻

There's now an additional Docker Compose file (docker-compose-arm64-support.yml) that can be used to run the application and tests on an ARM64 (e.g. MacBook Pro with M1) machine:

• Start the infrastructure with: docker-compose -f ./docker-compose-arm64-support.yml for running the application locally

UPDATE (2022-04-29): There's no need for an additional Docker Compose file anymore as all Docker images come with arm64 support 🏆
