[VVP] Updates to VVP test-engine

Removing module level variables. These can cause import errors if certain modules are not imported "properly". Removing these lets developers import modules as-needed.

Add support for VNF category. The VNF category is looked up based on the category chosen by the VSP.

Increase test coverage.

Update ovp testsuite based on these changes.
