Bump to version 0.2.0.

Release notes.

Bump the ISO URL.

Have DNS testing working, need feedback on structure, thanks

Build conntrack as part of the iso.

Use "go list" to calculate transitive dependencies.

Make the dashboard service listen on a NodePort.

Add an integration test for the addon manager and dashboard.

This makes it easier to access the dashboard.

Add a flag to hide libmachine logs.

Fix logging for cluster_env_test.

Wait a few seconds for the cluster to become healthly.

Added ssh integration test and updated RunCommand in util.go

Add a retry utility to util, and use it to retry cluster creation.

This fixes the phantom errors we see on ubuntu that are fixed by rerunning start.

Set the proxy mode to iptables.

Fix "make integration".

Adding logs command integration tests

This passes all conformance tests that pass with the other mode.

Unmark the DNS Service and Endpoint as cluster-services.

Added env command integration test

These logs often reference docker-machine itself, which is confusing to
users. We should log everything we need to ourselves.

This label causes the addon-manager to delete them. We can't let the addon-manager
create these either, because it doesn't support endpoints.

Fixed issue with wrong static-pods location in Makefile

Switch logging in dns.go to glog.
