added the feature to auto generate spec report for ci
added the feature to auto generate spec report for ci

1. added spec report generation feature for ci for:
      atmos, base, filesystem, mongodb, mysql, neo4j,
      postgresql, rabbit, redis, serialization_data_server,
      service_broker, vblob

2. added a namespace called ci with task spec:
    for the new unit test with reports generated, do:
      bundle exec rake ci:spec
    the reports would sit in spec_report in the xml format, which can be recognized by jenkins.
