Upgrade controller runtime package

[JessicaGreben]

The cloud team would like to upgrade the version of the controller-runtime package to sigs.k8s.io/controller-runtime v0.19.2 because we are encountering this error when we try to build our code with ako in this PR:

# github.com/aerospike/aerospike-kubernetes-operator/api/v1
../../../../pkg/mod/github.com/aerospike/[email protected]/api/v1/aerospikecluster_webhook.go:38:57: cannot use admission.NewDecoder(mgr.GetScheme()) (value of type admission.Decoder) as *admission.Decoder value in struct literal: admission.Decoder does not implement *admission.Decoder (type *admission.Decoder is pointer to interface, not interface)

We tried to downgrade sigs.k8s.io/controller-runtime v0.17.3 on our side, but it resulted in errors from other packages we are using (for example github.com/external-secrets/external-secrets) that also require a higher version.

Some of the breaking changes in sigs.k8s.io/controller-runtime going from 0.17.3 to 0.19.2 are:

1. admission.Decoder is now an interface instead of a struct (see PR)
2. The options.AddFrom method is deleted (ref: docs). This change is causing the CI for this PR to fail since the AddFrom method is used here: https://github.com/aerospike/aerospike-kubernetes-operator/blob/master/cmd/main.go#L79. It seems like a big undertaking to replace that. I'm not sure whats the best path forward.
