Andres Freund 3223b3c92d Centralized Connection Lifetime Management. 
Connections are tracked and released by integrating into postgres'
transaction handling. That allows to to use connections without having
to resort to having to disable interrupts or using PG_TRY/CATCH blocks
to avoid leaking connections.

This is intended to eventually replace multi_client_executor.c and
connection_cache.c, and to provide the basis of a centralized
transaction management.

The newly introduced transaction hook should, in the future, be the only
one in citus, to allow for proper ordering between operations.  For now
this central handler is responsible for releasing connections and
resetting XactModificationLevel after a transaction.
