Nova-compute will crash if it cannot connect to VC on startup

[Tracy Jones]

the nova-compute process with the VCDriver will crash on startup if it cannot reach vCenter or receives an error from vCenter. In production, VC and nova-compute may startup around the same time. nova-compute should wait for VC to be accessible instead of crashing.

    VMware: nova-compute crashes if VC not available

    The ESX driver gets a connection to vCenter Server on startup.
    Currently, if vCenter Server is not available, nova-compute crashes.
    This fix adds slow retry when nova-compute starts before vCenter
    Server is available. The errors are logged in case the issue is
    a mis-confiugration of vCenter Server

    Fixes: bug #1192016
