GitHub issue 1320 - support PDO::ATTR_EMULATE_PREPARES at the connection level
--DESCRIPTION--
Supports PDO::ATTR_EMULATE_PREPARES at the connection level but setting it to true with column
encryption enabled will fail with an exception. Also, the options in the prepared statement will
override the connection setting.
