Do not use MYSQL_OPT_RECONNECT for MySQL 8.0.34+ clients

Beginning with MySQL 8.0.34, the automatic reconnection feature is
deprecated and disabled by default.

When MYSQL_OPT_RECONNECT is used then client prints to stderr message:

  WARNING: MYSQL_OPT_RECONNECT is deprecated and will be removed in a future version.

Fixes: #191
