Bug description:
  Currently Masakari host-monitor only grep the `crmd` status of real node via `cibadmin -Q` command.
  In case of pacemaker_remote, the `crmd` attribute is not existed, so remote node always marked in `None` state.

  Below is an example xml status of remote node:
  <node_state remote_node="true" id="cpu1" uname="cpu1" crm-debug-origin="remote_node_init_status" node_fenced="0">
        <transient_attributes id="cpu1">
          <instance_attributes id="status-cpu1"/>
        </transient_attributes>
      </node_state>
      <node_state remote_node="true" id="cpu2" uname="cpu2" crm-debug-origin="remote_node_init_status" node_fenced="0"/>

  And the log from masakari hostmonitor:
  2017-10-30 14:15:44.679 1813 INFO masakarimonitors.hostmonitor.host_handler.handle_host [-] Recognized 'cpu1' as a new member of cluster. Host status is 'None'.
