Ability to reduce data exposed via exception

[royxact]

Hi team,

We just had a PT done to our system.
Specifically the part of our system which uses Superset.
The problem is with the error message clickhouse-connect returns.
It includes both the server name and the clickhouse version. This is great in some cases, but no so good for security as end users of superset are not supposed to know these details. Can you add a flag to reduce the error messages to just the minimal SQL error?

Thanks!
