docker sc 版本不是最新的

Describe the bug servicecomb-java-chassis 2.x 版本和 docker sc 的版本规则不匹配

问题是：docker 的 service-center版本太低了

  ~ docker run servicecomb/service-center -it /bin/bash
2020-03-31T03:46:20.282Z    INFO    core/config.go:102  service center is running simultaneously with 2 CPU cores
2020-03-31T03:46:20.283Z    INFO    version/version.go:50   Version: 1.1.0
2020-03-31T03:46:20.284Z    INFO    version/version.go:51   Build tag: 20190507120440.1.1.0.c6821d1d
2020-03-31T03:46:20.284Z    INFO    version/version.go:52   Go version: go1.11.2
2020-03-31T03:46:20.284Z    INFO    version/version.go:53   OS/Arch: linux/amd64
