find heavily used tools with large runtime

I would like to start optimizing some tools. I think we can find some BA and MA students to optimize our tool stack and with that waste fewer resources.

To prepare a query like `gxadmin query tool-usage` but with a min/avg/max runtime column would be super useful.

Start from the existing `gxadmin query tool-usage` command and inspect how its query and output are assembled. Add min/avg/max runtime columns and verify that the command reports them for tool usage; the issue does not name a file or test.
