Move basically manual test cases to smoke

[TachunLin]

For the node_driver feature in smoke test suite.

A suggestion is we can change the folder name to rancher_integration to allocate all relative test plans in it.

And we can add some basic rancher integration test plans like the followings:

• https://harvester.github.io/tests/manual/harvester-rancher/02-integrate-rancher-from-harvester-settings/
