Now, instead of reams of unreadable command output, we get a nice set of stages:
[ 0/13] Deleting existing test cases directory
[ 1/13] Creating file size testcases
[ 2/13] Creating file name extension testcases
[ 3/13] Creating file names testcases
[ 4/13] Creating special file kind testcases
[ 5/13] Creating symlink testcases
[ 6/13] Creating user and group testcases
[ 7/13] Creating file permission testcases
[ 8/13] Creating date and time testcases
[ 9/13] Creating extended attribute testcases
[10/13] Creating Git testcases (1/3)
[11/13] Creating Git testcases (2/3)
[12/13] Creating Git testcases (3/3)
[13/13] Creating hidden and dot file testcases
The scripts have been moved out of the Vagrantfile because it was getting long and they're more readable this way.
