Update BestPractices.md to remove alpine user 

Since the `node` user was added to the alpine variant, there is no need to recommend that they need to create the `node` user. In fact, it would break. Only the `onbuild` variant does not have the user.

I also added the `USER node` syntax to show how to [set the user](https://docs.docker.com/engine/reference/builder/#user) in the dockerfile.

FROM node:4.1.2-onbuild
# Add our user and group first to make sure their IDs get assigned consistently
RUN groupadd -r node && useradd -r -g node node

When using the `alpine` variant, add the user like so:
```Dockerfile
FROM node:7.3.0-alpine
RUN addgroup -S node && adduser -S -g node node
