    Correct the interval between two reports
    
    Currently the interval between two reports is wrong. For example, with
    below setting in file metering_agent.ini
    measure_interval = 30
    report_interval = 600
    
    The Ceilometer will get the reports from meter-agent per 630 seconds. The
    reason is the test condition is wrong in the code, we should use >=
    instead of >
    
    add a unit test
    neutron.tests.unit.services.metering.agents.test_metering_agent.
    TestMeteringOperations.test_notification_report_interval
    to test the report interval

Title:
  the interval between two neutron metering reports are not  correct

Status in neutron:
  Fix Released

Bug description:
  the interval between two neutron metering reports are not  correct.
  For example, we have below configuration in file metering_agent.ini

  # Interval between two metering measures
  measure_interval = 30

  # Interval between two metering reports
  report_interval = 600

  then go to the ceilometer to dump all neutron metering samples, the
  reports interval will be 630 seconds. Below are some dump result:

  From above ceilometer result we can know the actual report interval is
  report_interval+measure_interval
