[local_storage] Add metric for minfs upgrade
This metric will be used to track the progress of an in-place minfs
partition upgrade. The metric is a simple counter (broken down by the
usual dimensions board/product/channel/version) which has several
"stages" which we can use to monitor how often the upgrade is attempted
and how often it completes successfully (by drop-off analysis).
