The Infinispan Server CLI should be extended so that it can be used to control/configure the operator and custom resource definitions.
The CLI should act as a `kubectl` plugin, i.e. installed as `kubectl-infinispan` so that it can be invoked as `kubectl infinispan ...` or `oc infinispan ...`
The CLI should be able to perform the following operations:

• install the operator CRD
• create CRs (cache service, caches, etc)
• transparently connect to a running cluster to perform interactive operations
