Apollo all-in-one deployment?

**Is your feature request related to a problem? Please describe.**
Currently, apollo suggests deploying 3 different microservices(apollo-configservice, apollo-adminservice, apollo-portal) for the production environment. It makes sense for medium and large companies.
However, for small companies which may have only tens of microservices, it's a big cost to deploy apollo in this structure.

**Describe the solution you'd like**
Provide a production-ready solution to reduce the resource usage, e.g. an all in one deployment.

**Describe alternatives you've considered**
There is a [quick start](https://github.com/apolloconfig/apollo-build-scripts) version, however, it's not production ready and the apollo portal is still a standalone process.
