Support for data distribution among a subset of datanodes
CREATE TABLE has been extended with the following clause:
CREATE TABLE ...
[ TO ( GROUP groupname | NODE nodename [, ... ] ) ]
This clause allows to distribute data among a subset of nodes
listed by a node list, or a group alias.
Node groups can be defined with CREATE NODE GROUP.
The base structure for this support was added with commit
56a90674444df1464c8e7012c6113efd7f9bc7db, but check of mapping of
subsets of node list was still missing for the management of join
push down and materialization evaluation in planner.

Fix for bug 3431570: crash with Hadoop and sqoop
This crash was happening at the execution of a RemoteQuery node
when trying to allocate memory for fresh handles taken from pool.
In this case allocation was made in TopTransactionContext.
However, in the case of sqoop, which is a Hadoop module creating an
interface with a db backend, it happened that TopTransactionContext
was NULL, leading to a crash of the node.
This commit switches the memory context to CurrentMemoryContext
and contains fixes for possible memory leaks related to barrier and
COPY.
Fix from Pavan Deolasee
