Add wait mechanism into linkerd-crds Helm chart

[jaygridley]

What problem are you trying to solve?

After the split of crds and control-plan helm charts in https://github.com/linkerd/linkerd2/issues/6620, there is no mechanism for how to wait for crds to be present in the cluster when installing in an automated way.

For example, when installing both charts using Terraform Helm provider there is no deterministic approach how to detecting if crds are present in the cluster and subsequent control-plane installation could fail.

How should the problem be solved?

Kubernetes Job could be added that will check the Kubernetes API for CRDs presence and its status. Then Helm release could leverage wait_for_jobs attribute.

Any alternatives you've considered?

N/A
