Bug description:
  [Impact]
  On openstack-dashboard login page(the first pace we face), there is unexpected graybar on top of the page.

  I've been analyzing this page and found below code affects to this
  symptom.

  body.md-default-theme, body, html.md-default-theme, html {
      color: rgba(0,0,0,0.87);
      background-color: rgb(250,250,250);
  }

  If I remove above background-color, It is ok.

  I also found that upstream doesn't have the same symptom.

  It seems that xstatic override css setting when generating it.

  Please see the screenshots attached below.

  And this is happening from UCA pike.

  [Test Case]
  1. deploy openstack env with juju,
  2. check openstack-dashboard login page

  [Regression Potential]
  This patch updated ubuntu theme only. It could show us broken css even in worst case. Restarting apache2 and memcached daemon is required.
