    Baremetal: Be more patient with IPMI and BMC

    Before we called 'power status; power on' in a loop which made the
    IPMI/BMCs not behave well. Also the total time we would wait (2.5
    seconds wasn't always enough). So make sure power on/off is only called
    once and wait up to 10 seconds for the power state change to go into
    effect.

    This patch has been tested on real baremetal using
    https://wiki.openstack.org/wiki/TripleO/TripleOCloud

    This bug is also linked to ironic so the change will be made there as
    well.
