Query converts TaskCanceledException to InternalServerError

[j82w]

There is a bug in the query code where it is converting the TaskCanceledException into a InternalServerError. The conversion is also not include the CosmosDiagnostics so it is not possible to see what is causing the TaskCanceledException.

Example exception:

Failure during tenant set refresh Microsoft.Azure.Cosmos.CosmosException: Response status code does not indicate success: InternalServerError (500); Substatus: 0; ActivityId: 00000000-0000-0000-0000-000000000000; Reason: (A task was canceled.); --->
