Merge branch 'feature/3.0' into feature/collector

* feature/3.0:
  Add mock-module test cases.
  fix compile issues
  Add Tomcat span, and singleTrace mock.
  Give a sample code of the first Mock trace.
  Add skywalking-sniffer-mock module. For testing sdk-plugin and collector(not merged yet) modules.
  Big refactor. Rename the api-module root package name .
  remove blank line.
  Refactor tags.
  Take Adrian Cole ’s advice, remove http prefix of tag. Maybe still need some improvements.
  Refactor code.
  add delegate method
