Bug Description

When separate threads are issuing power on/off requests on a VM (possibly through spawns, deletes, power_on, power_off, reboot, etc.), timing issues can arise when threads are retrieving and acting on the VM state. nova-powervm should synchronize power on/off operations (per instance) to avoid this.

    Synchronize power ops

    When separate threads are issuing power on/off requests on a VM
    (possibly through spawns, deletes, power_on, power_off, reboot, etc.),
    timing issues can arise when threads are retrieving and acting on the VM
    state. This change set synchronizes power on/off operations per
    instance to avoid this.

    A side-effect of this change is that the PowerOn Task no longer requires
    the lpar_wrap from prior Tasks.
