Chef::Knife::UI#confirm

Not the ideal signature for a function but we need to stick with this
for now until we get a chance to break our API in Chef 12.

question => Question to print  before asking for confirmation
append_instructions => Should print '? (Y/N)' as instructions
default_choice => Set to true for 'Y', and false for 'N' as default answer
