Docker image for ARM architectures

[dlvenable]

Is your feature request related to a problem? Please describe.

The Data Prepper Docker image is only available for x86 architectures presently. It is written in Java and should be able to run on ARM.

Describe the solution you'd like

Provide an ARM architecture Docker image. This should be done as a Docker multiarch image so that users can follow the same instructions regardless of their architecture.

Tasks

• Support a local ARM image build #3352
• ARM distributions via tar.gz #2571
• Update Jenkinsfile to copy ARM image - Support ARM archives for Data Prepper opensearch-build#5977
• Run tests on ARM #2294

Since there are a lot of benefits of using Graviton instances in AWS, in both EC2 or EKS. It would be Nice to support running this container image in ARM architectures.

Need this also to run on our EKS clusters (Graviton nodes)
As AWS so much promoting they Graviton instances strange that DP still has no ARM image ready

[dlvenable]

It appears that the Gradle plugin that Data Prepper uses to build Docker images supports multiarch through buildx.

palantir/gradle-docker#528

Great finding @dlvenable!
But then need to update info about image so it would be clear. ETC: https://hub.docker.com/r/opensearchproject/data-prepper/tags - shows that only supported arch is: linux/amd64

@dlvenable Seems like I miss understood so there is possibility to build multi arch but only x64 is beeing built. So if this is small change maybe it could happen soon?
