ceilometer dashboard Stats page error

[huangjianbo]

When I try to open the "stats" page of dashboard, I get the dialog of "An error occurred. Please try again later." and "No data available." is showed. At last, I find there is a mistake in /usr/share/openstack-dashboard/openstack_dashboard/dashboards/admin/metering/templates/metering/stats.html ：

<div class="chart"
    data-chart-type="line_chart"
    data-url="{% url 'horizon:admin:metering:samples'%}"
    data-form-selector='#linechart_general_form'
    data-legend-selector="#legend"
    data-smoother-selector="#smoother"
    data-slider-selector="#slider">
</div>

The "data-url" should be "data-data", otherwise the d3linechart will get null value and report error.
My problem was solved by correcting it.

For master this is no longer valid because the code for metering was removed from horizon. See https://review.openstack.org/#/c/399298/

The metering panel was removed from Horizon, and was deprecated for several cycles before that.
