Do not need quotes in org name
Change vdc_name to vdc_name_1 and add extra params

This is required for the storage profile tests in launcher. Ideally the names would be even more consitent, e.g. vdc_1_name rather than vdc_name_1 - this will follow.
Move set-up and tear-down outside specific context

As same set-up and tear-down will be required for other testing contexts.
Rename tests/config that are not launcher-specific
Test vCloud Launcher-specific parameters

This adds a test that ensures that all parameters required to test vCloud Launcher are retrievable. Ideally this would be hooked up to the test itself but for now, it is enough to check that these parameters can be passed and obtained.
