SetupInstance sets up the specified GCE Instance for E2E testing and returns a handle to the instance object for future use.

SetupNewDriverAndClient gets the driver binary, runs it on the provided instance and connects a CSI client to it through SHH tunnelling.

TeardownDriverAndClient closes the CSI Client connection, closes the SSH tunnel Kills the driver process on the GCE instance, and cleans up the remote driver workspace.

ClientConfig contains all the parameters required to package a new driver and run it remotely on a GCE Instance.

InstanceConfig is the common bundle of options used for instance creation.

TestContext holds the CSI Client handle to a remotely connected Driver as well as a handle to the Instance that the driver is running on.
