Import an activity without user data

Title: Ability to import an activity into any course without user data.

As a teacher,
I want to be able to import an activity into any course without user data,
so that I can reuse the same activity (with preserved settings) when creating/editing several courses.

--------------

Acceptance Criteria

Please explain what has to be done for the user story to be marked as complete. They’re commonly referred to as scenarios or detailed explanations of what has to be done. You can have multiple scenarios per user story.

Scenario A:
I should be able to import an activity, with all settings preserved, into any course without user data easily and quickly.

Stretch Goal:

Extend to more than one activity

Priority: SML / *LRG*

Notes:

Restore interface is complex. Most of the time teachers just want to import the last year activities into a course without user data. Already doing this for some modules.
Does course backup - restore already allow teachers to do this efficiently?
