Testing K-in-D on Podman

Testing Kind on Podman on Apple M1 & Intel

Goals:

• Basic testing of Podman and bridge networking (ability to connect back to host services)
• Basic testing of KinD (Kubernetes in Docker) with podman
• Test framework for Istio
• Anything else that's fun

Known Issues

• Podman support is experimental
• Mapping of local files is not yet supported (4.0.2)
• On M1, containers must be for linux/arm64 (exec error when runnning Intel containers on M1)
