This change adds the possibility to write acceptance tests with multi virtual machine support. It's done keeping the virtual machines objects stored in a test attribute (dictionary). This dictionary shouldn't be accessed directly but through the new method added `get_vm`. This new method accept a list of args (that will be added as virtual machine arguments) and an optional name argument. The name is the key that identify a single virtual machine along the test machines available. If a name without a machine is informed a new machine will be instantiated. The current usage of vm in tests will not be broken by this change since it keeps a property called vm in the base test class. This property only calls the new method `get_vm` with default parameters (no args and 'default' as machine name).
