Feature Request: build multi-architecture Docker images

[justenwalker]

Docker images distributed on docker hub for concord components are single-CPU architecture targeting linux/amd64.

• walmartlabs/concord-agent
• walmartlabs/concord-agent-operator
• walmartlabs/concord-ansible
• walmartlabs/concord-base
• walmartlabs/concord-console
• walmartlabs/concord-server

Given the growing popularity, and low cost of arm64 CPUs, it would be good to make these architecture types available.
This is also nice to support local development on Apple Silicon Macs which have native ARM64; which currently must rely on amd64 emulation to run.
