Importable End-To-End Test Suite (#758)

* Rename VK to chewong for development purpose

* Rename basic_test.go to basic.go

* Add e2e.go and suite.go

* Disable tests in node.go

* End to end tests are now importable as a testing suite

* Remove 'test' from test files

* Add documentations

* Rename chewong back to virtual-kubelet

* Change 'Testing Suite' to 'Test Suite'

* Add the ability to skip certain testss

* Add unit tests for suite.go

* Add README.md for importable e2e test suite

* VK implementation has to be based on VK v1.0.0

* Stricter checks on validating test functions

* Move certain files back to internal folder
