v0.27.0

v0.27.0 is the "first" aks-engine release!

Why "first"?

• Because aks-engine is a code-continuation of acs-engine, it's functionally the next release of a long-running project.

Why v0.27.0 as an initial release?

• Again, as a way of more clearly communicating that this is the next release for the pre-existing user community, we are rev'ing the minor version using the most recent acs-engine version as our "last minor release" baseline.

What's new?
