Add multi-arch support for golang-http-template

Description

Add multi-arch support for golang-http-template

How Has This Been Tested?

Multi-Arch function build

# Pull golang-http multi-arch template
faas-cli template pull https://github.com/utsavanand2/golang-http-template

# Create new golang-middleware function named hello-http
faas-cli new --lang golang-middleware --prefix utsavanand2 hello-http

# Create a shrinkwrapped build of function
faas build -f hello-http.yml --shrinkwrap

# Use buildx to build and push function image to container registry
docker buildx build \
--platform linux/amd64,linux/arm/v7,linux/arm64 \
--output "type=image,push=true" \
--tag utsavanand2/hello-http:latest build/hello-http/

# Deploy hello-http function to a Raspberry Pi k3s cluster running OpenFaaS
faas deploy -f hello-http.yml

Making sure faas-cli up works the same way as before.

# Build, push and deploy hello-http function to minikube (amd64 arch)
faas up -f hello-http.yml

Can we upgrade to golang:1.13-alpine3.12 please?

[alexellis]

Same as previous comment. Please let's move to 3.12?

[alexellis]

LGTM. Ready to merge, but please update to 3.12 in a follow-up PR.

[utsavanand2]

Sure I'll upgrade the Golang version in a new PR
