Add test for cog migration with GPU (#2301)
* Add test for cog migration with GPU
* Remove validate and complete
* This adds the wrong CUDA/CUDNN versions to the
config
* Resolving this at runtime works better
* Trim the output of the python code change
* Only compare the trimmed string
* Add unit test for gpu migration
* Add ability to get config without completion
* In migrate we don’t want to complete the users
config with default values.
* Change integration test to just check gpu config
* Remove debug print
