`bool` `maxdb::ping`

Checks whether the connection to the server is working. If it has gone down, and global option `maxdb.reconnect` is enabled an automatic reconnection is attempted.

This function can be used by clients that remain idle for a long while, to check whether the server has closed the connection and reconnect if necessary.
