Apache ServiceComb (incubating) Service-Center 1.0.0-m1

Major improvements:

• Java Chassis can now use Apollo as configuration center. Users can now
  change configurations like load balancing policy and those changes will
  come into effect on the fly.
  See here for more
  details.

• Metrics was re-factored. We now uses events for collecting invocation data
  instead of Hystrix. This reduces the performance penalty of computing
  metrics.
  Metrics can now be fetched via '/metrics' using HTTP.
  See here for
  more details.

Other Noticeable Changes:

• The Java Chassis libraries are now under group "org.apache.servicecomb".
• We provide out of the box metrics support now. Prometheus is supported.
• Configuration center was re-factored and moved out from foundation.
  Support for Apollo was added.
• Users can now use Object type for calling services.
• Users can now use Generics for calling services.
• Better integration with Spring MVC.
• Upgraded to zipkin2 internally, Java Chassis can now work with zipkin
  server v1 and v2.
• We are in the process of supporting reactive programming. Pojo consumer
  and provider now supports CompletableFuture.
