    Fix libvirt watchdog support

    Using the flavor extra_specs property "hw_watchdog_action" was broken.
    Scheduling of a new instance always failed with NoValidHostFound error
    because of ComputeCapabilitiesFilter, which treated this property as a
    host capability to be checked.

    Commit f0ff4d51057080e769407e873e5ed212f15b773d caused the problem.

    To fix this watchdog_action property is put into 'hw:' scope, so
    that it will be ignored by ComputeCapabilitiesFilter in scheduler and
    handled in libvirt driver. The doc must be fixed accordingly.

    Now driver accepts both 'hw_watchdog_action' and
    'hw:watchdog_action', tests were edited for these cases.
    Were added TODO items to delete the compat code in L release.
