dataStorage vs persistence value

[kfox1111]

The very common convention is to have a persistence flag for dealing with volumes. This chart is using dataStorage instead. We should probably consider changing this flag before 1.0.

We are naming the things as they are named on the Spire side. So dataStorage is named because of the dataStorage config option in the spire config.

Its a helm chart though and the convention that most helm users expect is persistence rather then dataStore. Which way will be less confusing to users?

We talked it over during the last meeting and decided to go with persistence.
