Attila Tajti b6baba23b0 pkg/blobserver/overlay: use better names for underlying storage
Use the names "lower" and "upper" from OverlayFS
instead of "base" and "stage".

Also make the deleted keyvalue (and thus support for deletion) optional,
and improve readability for the StatBlobs method.

Attila Tajti b71c054373 pkg/blobserver/overlay: add “overlay” blobserver type
The blobserver uses a base blobserver in read-only mode,
and uses another stage blobserver to record changes.

In a sense it is a read-write view on the master
blobserver that never changes base itself.
