CLI: Automate dependency PVC creation

To add dependencies to a Infinispan cluster deployed via the operator, it's necessary for a PVC to be created and data added before then creating the Infinispan CR.

Steps:
1. Create PVC
2. Mount PVC to pod
3. Copy files to pod via `kubectl cp`
4. Shutdown pod
5. Create Infinispan CR with `spec.dependencies.VolumeClaimName`

The CLI should automate steps 1-4, allowing a user to simply provide the PVC spec as well as a list of local files to upload.
