Provide user utilites

[iocanel]

We have lots of utilites that are mostly meant for internal consumption.
The lack of a non-internal utility for doing simple things with Kubernetes resource has led a lot of people using KubernetesHelper which was always meant to be replaced by the client.

We should create a utility class that provides at least the following:

• Sanitize strings based on the Kubernetes regex for:

  • resource names
  • resource labesl
  • resource annotations

• Null safe operations for:

  • name
  • namespace
  • labels
  • annotations

Maybe more need to be added, but for now, these would suffice.
