func UpgradeableStoreLoader(upgradeInfoPath string) StoreLoader

UpgradeableStoreLoader can be configured by SetStoreLoader() to check for the existence of a given upgrade file - json encoded StoreUpgrades data.

If not file is present, it will peform the default load (no upgrades to store).

If the file is present, it will parse the file and execute those upgrades (rename or delete stores), while loading the data. It will also delete the upgrade file upon successful load, so that the upgrade is only applied once, and not re-applied on next restart

This is useful for in place migrations when a store key is renamed between two versions of the software. (TODO: this code will move to x/upgrades when PR #4233 is merged, here mainly to help test the design)
