postgres_fdw: Add support for parallel abort.
postgres_fdw aborts remote (sub)transactions opened on remote server(s)
in a local (sub)transaction one by one when the local (sub)transaction
aborts. This patch allows it to abort the remote (sub)transactions in
parallel to improve performance. This is enabled by the server option
"parallel_abort". The default is false.
