Kylin upgraded from springmvc architecture to spring boot architecture

Hi Team:

Kylin is based on the spring mvc architecture, but the spring mvc configuration is more complicated. It is cumbersome when integrateing new components.

Now， The mainstream of the industry has been based on the spring boot architecture. Spring boot can be automatically configured to reduce the complexity of project integration; promote the expansion and implementation of microservice architecture. More and more project architectures have been upgraded from springmvc to spring boot.

Kylin can also be upgraded from the springmvc architecture to the spring boot architecture.

Do you have any suggestions?
