Add a tag on queries launched by the export option

**Is your feature request related to a problem? Please describe.**
For security reasons, I check my entire MySQL fleet to dump data. The problem with Cloudbeaver is that a data export is a simple select *.

**Describe the solution you'd like**
Is it possible to add a comment to all export requests since they can be identified? For example SELECT /* cloudbeaver export */ ... like can mysqldump do it? And if it is possible, I would like the comment to be present by default, not that it is an option to activate.
Or, if it's simpler, use the integrated cloudbeaver logger to log who launched an export of what.
