Naming consistency in dev-cluster

[steezeburger]

I decided upon some naming conventions after having already done the celestia-local work, so I need to go back and make some things consistent with the newer work.

• consistent naming for PersistentVolumes and PersistentVolumeClaims
  • {{pod name}}-{{service name}}-pv
  • {{pod name}}-{{service name}}-pvc
• use plural version of words for kubernetes yaml filenames, even if there is only one resource in the file at the moment
  • volumes.yaml, storageclasses.yaml, etc
• consistent naming for storage values in values.yaml

We've had a lot of work done to our charts. I don't think this is relevant anymore. We can reopen if it is.
