'''
Create GCE resources for use in integration tests.
Takes a prefix as a command-line argument and creates two persistent disks named
${prefix}-base and ${prefix}-extra and a snapshot of the base disk named
${prefix}-snapshot. prefix will be forced to lowercase, to ensure the names are
legal GCE resource names.
