in order to know which blob is 'real' (has content)
we need to know which was the first blob inserted in cache,
because that is always the real one.
because we can not modify the keys order in boltdb we'll do this
by marking the first blob inserted with a value
when GetBlob() return the blob which is marked
when PutBlob() if is the first one, mark it
when DeleteBlob() in case deleted is marked then mark the next blob

Because s3 doesn't support hard links we store duplicated blobs
as empty files. When the original blob is deleted its content is
moved to the the next duplicated blob and so on.

results of the linter.
