replace heketi client implementation

This change makes use of github.com/sigma/heketi branch k8s-standalone, which is
a stripped down, k8s-specific version of github.com/heketi/heketi with:
- only useful client-code, which sidesteps the issue of heketi improperly
  vendoring k8s (which prevents vgo from working, see kubernetes#65683)
- uses only Apache 2 licensed code (which addresses partially
  kubernetes/sig-release#223)

For details, see
