v0.25.0 is a regular minor release

Update docker runtime to moby from docker-engine: #3896 (@jackfrancis)

Moby will replace docker-engine as the docker runtime ("containerRuntime": "docker") for all Linux nodes with the exception of nvidia driver-backed N series VM SKUs, which have a hard docker-engine dependency.

This is a backwards-compatible change for all pre-existing docker-backed clusters.

4.15.0-1030-azure kernel fix: #4178 (@jackfrancis)

This addresses a long-standing kubernetes bug w/ DNS lookups on alpine-based images. See
kubernetes/kubernetes#56903

Don't require VM tags during upgrade/scale: #4100 (@mboersma)

For known operational scenarios, acs-engine-delivered vm tags are no longer a requirement to upgrade/scale clusters. We maintain the recommendation to keep tags unchanged, but in the event that they are removed, the upgrade/scale operations should be resilient against this.

nvidia drivers resilience: #4113 (@jackfrancis)

We expect this refresh of the runtime installation logic to yield fewer flakes during cluster provisioning.

Custom manifest yamls: #4092 (@pidah)

Experimental "bring your own static k8s componentry definitions" functionality — Use at your own risk!

conformance-passing features by default: #4133 (@ritazh)

Minor changes to increase cluster conformance configuration by default.
