* get rid of unneeded files * don't reuse batch callback * move out storage contract handlers * wip * add storage handler, to handle storage contracts interactions * split out node tests * a bit more cleanup * remove storage handler, move back into node * add missing raises: * wip: add support for rebuilding slot * split out tests * wip * rework indexing strategy to return an iterator * convert to seq * minor api change (meh, might revert) * steping strategy should not die * allow fetching batches for manifests and indicies * restored expiry update * restored expiry update functionality * avoid closing datastores twice * correct wrong rename * fixes sigsegv
