Expand count distinct support

We can now support more complex count distinct operations by
pulling necessary columns to coordinator and evalutating the
aggreage at coordinator.

It supports broad range of expression with the restriction that
the expression must contain a column.

Move processing each part of the query into its own functions

This commit doesn't change any of the logic at all.

Instead, the goal is to:

 * Get rid of any code duplication
 * Incremental changes to the optimizer made it slightly hard
   to follow the code, improve that and make it easier to
   implement new features
 * Simplify the code by moving each part of query processing (e.g.,
   DISTINCT, LIMIT etc) into its own function
 * Make the interaction between each part of the query more
   obvious (e.g., How DISTINCT affects LIMIT etc)

Unify extendedOpNode Processing

Before this commit, we had a divergence among
the creation of master/worker extended op nodes.

This commit moves the related parts into a single place
and allows the creation of master/extended op nodes to
share a common data structure.
