Title:
  logging a warning when someone accesses / seems unnecessary and
  wasteful

Status in Glance:
  In Progress
Status in Glance kilo series:
  New
Status in Glance liberty series:
  In Progress

Bug description:
  Our load balancer health checks (and other folks too) just load the
  main glance URL and look for an http status of 300 to determine if
  glance is okay. Starting I think in Kilo, glance changed and now logs
  a warning. This is highly unnecessary and ends up generating gigs of
  useless logs which make diagnosing real issues more difficult.

  At the least this should be an INFO, but ideally there's no point in
  logging this at all.
