[pxc-db] Change default timeouts

* Increase default net_read_timeout and net_write_timeout

net_write_timeout limits the max size of binlog sent to mysqlbinlog

180s in my tests were enough for 1GB binlog file

* Set connect_timeout to 30s

* Set wait_timeout and interactive_timeout to the same values as in MariaDB
