Fix subquery closing in mount, improve namespace.Query

Implemented cross-ds query in mount datastore

Log more in LogDatastore

add non-channel query iterator method

This avoids the use of a channel.

Avoid creating unnecessary strings when key is already in correct format

Add RawKey function and make use of it.

Avoids some unnecessary creation of strings.
