Update NPD version to v0.3.0-alpha.0 in kubemark.

@wojtek-t @shyamjvs Update the NPD version in kubemark.

I just built the alpha release https://github.com/kubernetes/node-problem-detector/releases/tag/v0.3.0-alpha.0.

And the PR kubernetes/node-problem-detector#79 is included.

However, I'm not sure whether 1 minute period is longer enough.

If it's still not longer enough, in fact we can extend it by split the resync and heartbeat:
* Every 1 minute, check whether there is inconsistency between apiserver and npd, and only update when there is inconsistency. (1 GET/m)
* Every > 2 minute, do forcibly update as heartbeat. (<0.5 PATCH/m)

And I can also make the sync period configurable after we finalize the sync mechanism.
