upgraderepo: allow extension to register preserved requirements Some requirement does not directly result from config and needs more advanced logic to be preserved. The current example is 'largefiles'. We add a hook point in the upgrade code so that extensions can handle these cases. The 'largefiles' extension will use it in the next changeset.
