Reboot of compute node breaks VMs with volumes

[Brent Eagles]

The virtualization drivers perform several steps in preparation for attaching a volume to an instances. These are transient in nature and if a compute node's host system is rebooted, the VMs with attached instances cannot start. These include file system mounts and iSCSI initiated connections. The problem is known to occur with libvirt, but may also exist with other virtualization technologies.

    Refresh volume connections when starting instances

    This patches adds network and block device information to the signature
    of the power_on method on the virtualization driver. The relevant call
    sites are also modified to provide the required information. The libvirt
    implementation of power_on has been altered to re-establish network and
    volume related connections.

    Fixes bug: 1188326
