Offer flexibility when cloning problems

[kiritofeng]

When cloning a problem, we should display more options, specifically:

• is_manually_managed should default to False if the user lacks the judge.change_manually_managed perm since the cloning user might lack OneDrive access
  • Otherwise, it should be configurable, with the default being what is currently set on the problem
• There should be a flag to specify if we copy over the organizations field
• The is_full_markup should be configurable, with it defaulting to False if the cloning user lacks judge.problem_full_markup, otherwise it should default to what is currently set on the problem
  • If the flag is changed to False and the cloning user lacks judge.problem_full_markup, a warning should show up stating that the problem might not be savable.
