Fixed nasty bug where if the storage fails to write a block we would clobber pending block data in memory by encrypting it in place. This was happening a lot when backing up to cloud and closing the laptop whihle the upload was going on. Added regression test and a rudimentary mechanism for fault injection in storage.

changed how index compaction works:
...
instead of having time-based naming, block manager will perform occasional compaction at startup time and delete unwanted blocks
The protocol is safe from concurrency standpoint and provides eventual consistency.
We only delete blocks after creating compacted blocks.
We retry loading index until (any) consistent index is fetched (possibly from cache) and all underlying blocks are also available, not necessarily the latest ones.
TODO - we need to periodically snapshot block index contents, so that if we have a bug somewhere in compaction code, we have a way of restoring working indexes.
