Sagar Bijwe 1df85e0039 nvs_flash: Version compatibility check for nvs storage
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.
