Description of problem:
The example go operator memcached-operator still use go 1.16 version.It might cause some problem about reflect.StructField during the build work.

Version-Release number of selected component (if applicable):
operator-sdk version: "v1.16.0-ocp", commit: "8dad7ace335d11ac79f1684e2a460dc34d910e0e", kubernetes version: "v1.22", go version: "go1.17.4", GOOS: "linux", GOARCH: "amd64"


How reproducible:
always

Steps to Reproduce:
1. create the go operator memcached-operator by https://docs.openshift.com/container-platform/4.9/operators/operator_sdk/golang/osdk-golang-tutorial.html#osdk-golang-define-api_osdk-golang-tutorial
2.build the operator
$make docker-build docker-push IMG=quay.io/xxxxx/memcached-operator:v4.10

Actual results:
1. Will meet error "sf.IsExported undefined (type reflect.StructField has no field or method IsExported"
$ make docker-build docker-push IMG=quay.io/olmqe/memcached-operator:v4.10
