upgrade: add support for experimental safe share mode

Recently we introduce the share-safe functionality which makes shares share
requirements and config of share source. This patch adds support to
`debugupgraderepo` command to upgrade repository to share-safe mode when
`format.exp-share-safe` config is enabled.
