By implementing a simpler Range, we can get rid of many methods
defined for storage.KeyValueStore.
Initially KeyValueStore was used to manage objects, hence it required
much more complex behaviour. However, we've moved away from this
implementation, hence we can significantly simplify everything.

`storage.KeyValueStore` requires ordered iteration, which redis
doesn't support natively. This would require loading all the keys
into memory and then processing them, rather than iterating over them
one-by-one.
This adds a temporary `IterateUnordered` to handle the migrations
more gracefully.

errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:
ERROR node stats service error: satellitedbs error: node stats database error: no rows
Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows
Would contain all the necessary information without the stutter.

Initially we duplicated the code to avoid large scale changes to
the packages. Now we are past metainfo refactor we can remove the
duplication.

Rename the functions that are prefixed with 'New' which connect with
Redis by 'Open' to make clear that they perform network operations.

Update the Redis dependency to use the last major production version.
The last version accepts a context parameter in all the network methods
so it allows us to pass it through them.
