Add ability to disable converting expressions to local filter for external queries
...
Sometimes it is undesirable to remove any expressions from WHERE, since
this may lead to reading the whole table, and this is pretty heavy job
for MySQL and PostgreSQL (even if you read only one column).
So external_table_strict_query had been introduced to prohibit this and
fail the query instead.
