Raise a WARNING for max_slot_wal_keep_size in pg_createsubscriber.

Raise a WARNING for max_slot_wal_keep_size in pg_createsubscriber.

During the pg_createsubscriber execution, it is possible that the required
WAL is removed from the primary/publisher node due to
'max_slot_wal_keep_size'.

This patch raises a WARNING during the '--dry-run' mode if the
'max_slot_wal_keep_size' is set to a non-default value on the
primary/publisher node.
