Description

see https://calcite.apache.org/avatica/docs/json_reference.html#openconnectionrequest
for openconnection request we can set info that is some key-value pairs .but for avatica-go we do not get the chance to post the info, though https://github.com/apache/calcite-avatica-go/blob/master/driver.go#L88 the code do set some info but after seeing the code https://github.com/apache/calcite-avatica-go/blob/master/driver.go#L61 we will know the info is nil, so the info will never be posted.

after reviewing the database/sql of go's source code, I found that the https://github.com/apache/calcite-avatica-go/blob/master/driver.go#L60 NewConnector will only go one input paramters that is dsn ,so if we want to post some info ,it is useless.
