Add guide for deploying BMI sample within docker(using docker swarm and kubernetes, etc).

[zenlint]

#99 try to give quick start for deploying sample within docker, no matter using docker compose or kubernetes.

Anyway, deploying within docker is a common way for deploying microservices.

I think it is better to put deploying in docker to a independent section after Advance microservice deployment to show generic recommended ways for deploying in docker. Considering ways as something like company-on-kubernetes.

[zenlint]

Materials may be added to BMI,

1. Dockerfile for building micorserivces in BMI;
2. YAML for doceker compose in BMI;
3. YAML for K8S deployment in BMI;

3 Steps(anyway, only three commands required) like,

1. Generate jar files;
2. Build docker images;
3. Depoloying;

It's good idea!
BTW, Where is the section ‘Advance microservice deployment’ ？

[zenlint]

@zhuhoudong Suggest you to add a independent section after Advance microservice deployment.
