Update santiy test to use ginkgo.

This have several benefits that:
1. Using consistent testing framework as e2e test
2. Able to define multiple test configurations per:
https://github.com/kubernetes-csi/csi-test/tree/master/pkg/sanity
3. Test results will be print to stdout as test runs as opposes to stuck
for a while and dump all results at once in the old way
