Automatic merge from submit-queue.
Initial bazel support
Builds on the 1.8 version bump
The "trick" is to strip the BUILD & BUILD.bazel files from the vendor-ed deps.
Will rebase after 1.8 version bump merges.

Add cluster spec to node user data so component config changes are detected
Related to #3076
Some cluster changes such as component config modifications are not picked up when performing updates (nodes are not marked as `NEEDUPDATE`). This change introduces the ability to:
1. Include certain cluster specs within the node user data file ~(`enableClusterSpecInUserData: true`)~
2. ~Encode the cluster spec string before placing within the user data file (`enableClusterSpecInUserData: true`)~
~The above flags default to false so shouldn't cause any changes to existing clusters.~
Following feedback I've removed the optional API flags, so component config is included by default within the user data. This WILL cause all nodes to have a required update to their bootstrap scripts.

Use SSL in ELB API server health check
This switch causes the ELB to perform a SSL handshake and makes the
`I0427 03:57:55.059255 1 logs.go:41] http: TLS handshake error from IP:PORT: EOF`
disappear from the apiserver logs.
Tested manually and everything looks ✅
Inspiration from https://github.com/kubernetes-incubator/kube-aws/pull/604

We move everything to the models. We feature-flag it, because we
probably want to change the names etc, and we aren't going to be able to
offer smooth upgrades until that is done.
