Uncommented the prereq-download provisioner

I had this commented out still, should be uncommented for first time
users.
Removed Shared Directory

Based on C835772's suggestion, pulled the files up one level so I don't
have the same shared directory name in the repo as what is built in the
vagrantfile by default. All files & dirs are now under Scenario1 and can
all be copied into the local shared directory created on the host.
