    Allow user to specify instance resume behaviour on host reboot
    
    The configuration option resume_guests_state_on_host_boot defines
    a global policy on whether or not to restart instances when a host
    reboots.  Because a host may be down for a significant period of
    time many cloud applications monitor their own instances and launch
    replacements restarting all instances is rarely the required behaviour
    
    The blueprint provides the user with a mechanism to specify the
    resume policy on a per instance basis.
    
    Supported values are:
      Default -  use system configuration value (current behaviour)
      Never   -  Don't resume this instance
      Always  -  Always resume this instance
    
    This is the first part of the blueprint which implements the resume
    decision.   The API extension will be provided in a separate commit
    
    Code is structured to allow a futher option of "Resume only if host
    has been down for less than xxx seconds" - but we need support from
    the ServiceGroup API for that.
    
    Partly implements bp: user-defined-resume
