Create a new dictionary for type_data in VMwareAPIVMTestCase class
Create a new dictionary for type_data in VMwareAPIVMTestCase class

The attribute type_data in VMwareAPIVMTestCase class is typically
set using one of the pre-defined flavors in test_flavors.py

Before this patch, any changes to the type_data was updating
the global variable DEFAULT_FLAVOR in test_flavors.py and
affecting the consequent tests. This patch creates a new dict()
so that updates to flavor spec is local to each test case.
