Description

Currently MAP and LOCAL queries are executed in completely different fashion. This leads to a number of bugs and discrepancies, not to mention obvious code duplication:

1. Local queries do not reserve partitions
2. Security checks might be missed for local queries (need to double-check).
3. Different event firing logic

Let's merge both flows:

1. Check security and other prerequisites
2. Reserve partitions
3. Get connection
4. Execute, firing events along the way
5. Release connection
6. Release partitions
