Support ARM64

[alittlec]

Description

Create a multi-arch image that supports arm64. (at present only amd64 supported)

Importance

It is possible to rebuild from source, but this is fragile and takes time, you also need to know the arch. upfront when deploying.

Suggestions for an improvement

Add a couple of additional entries to the build-go section:

CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build \
	-ldflags "-X github.com/$(REPO)/pkg/version.Version=$(VERSION) -X github.com/$(REPO)/pkg/version.GitSHA=$(GIT_SHA)" \
	-o bin/$(PROJECT_NAME)-linux-arm64 cmd/manager/main.go
CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build \
	-ldflags "-X github.com/$(REPO)/pkg/version.Version=$(VERSION) -X github.com/$(REPO)/pkg/version.GitSHA=$(GIT_SHA)" \
	-o bin/$(EXPORTER_NAME)-linux-arm64 cmd/exporter/main.go

@alittlec would you like to raise a PR for the changes?

[mmoscher]

@alittlec + @anishakj PR is raised, however I'm not sure if this will work at all because the available GHA CI pipeline is not used at all (IMHO). Cf. https://github.com/pravega/zookeeper-operator/pull/504

Hello,

Since I do not want to use Docker Hub. I have a different approach using GHA and docker image is saved to GHCR: https://github.com/pravega/zookeeper-operator/compare/master...patrickdung:pravega-zookeeper-operator:master?diff=unified

Note I disabled the E2E test because it would took about 1 hour to finish. Not submitting PR because the changes are only suitable for my needs. Feel free to adopt any changes.
