Replace use of <center> tag in RouterRules Grid template

[Chad Roberts]

In openstack_dashboard/dashboards/project/routers/templates/routers/extensions/routerrules/grid.html the <center> tag is used. As discussed in https://review.openstack.org/#/c/126141/10 the <center> tag should be stripped and the formatting should be handled via CSS.

[Sergey Gotliv (sgotliv)]

Tag <center> is deprecated in HTML 4.0 and totally not-supported in HTML 5.0. I agree that it should be replaced with appropriate CSS style.

[Gary W. Smith (gary-w-smith)]

+1 Fortunately <center> is still supported by all major browsers, per http://www.w3schools.com/tags/tag_center.asp
