Is your feature request related to a problem? Please describe.
When I need to iterate a cursor to process hundred thousands or even millions documents, it's important to make sure that the cursor session will not timeout until the process over, but the QueryI interface doesn't support til now.

Describe the solution you'd like
Add a NoCursorTimeout(n bool) QueryI method to the QueryI interface and use it in the Cursor() and All() methods.

Describe alternatives you've considered
None.

Additional context
None.
