Cannot enable multiturn extraction in QnA

[zxyanliu]

Describe the bug

It seems that multiturn is not supported by importing URL when creating a QnA kb in Composer. It is supported when creating a KB from scratch and after edits to its .qna file. We should consider removing the multiturn extraction checkbox to avoid customer confusion and anxiety in the KB creation flow.

Version

The main branch as of October 29, 2020

Browser

• Chrome

OS

• Windows

Expected behavior

We can bring back the multiturn extraction checkbox when multiturn qna is supported by importing URL when creating a QnA kb in Composer.

Screenshots

Importing URL with multiturn extraction checked in Composer: There is no hierarchy and tested multiturn did not work.

Importing URL with multiturn extraction checked in QnA portal: See the hierarchy and tested multiturn worked.

Additional context

Additional description and clarification of how to use multiturn qna will be covered in the docs.

This is a regression bug in bf-lu package, I'm following up with @feich-ms . I guess no UX issue here.
