[GitHub] helix pull request #278: [HELIX-771] More detailed top state handoff metrics

GitHub user zhan849 opened a pull request:

    [HELIX-771] More detailed top state handoff metrics

    
    Added more details about top state handoff to distinguish helix latency and user latency
    
    
    We define there are 2 types of handoff
    - Graceful handoff (controlled top state handoff, i.e. disable instance, load balance, etc)
    - Non-Graceful (uncontroller top state handoff, i.e. node crash, etc)
    
    
    For graceful handoff, we record total handoff latency and user latency
    For non-graceful handoff, we record total handoff only
    
    
    Moved top state handoff metrics to an independent stage to make logics cleaner.\
    Refactored TestTopStateHandoffmetrics to make it cleaner and more json more natively
