Replaced heat stack yaml files by individual server creation

Replaced heat stack yaml files by individual server creation

There is now a new file (rapidVMs.vms) describing how many VMs need
to be created. You can specify the same flavor values in the [DEFAULT]
section or specify specific flavors per VM.
The heat stack yaml files are removed.
