[SR-Users] Losing MySQL connections

the ping option is set to the libmysqlclient, kamailio itself doesn't do
anything in this regard. Iirc, in some old versions of the library, this
option didn't work.

On the other hand, kamailio should try to reconnect if disconnected, but
in this case it seems that the connection was broken during the query.
