    Use POST not GET for keypair generation
    
    This patch fixes the Cross-Site Request Forgery (CSRF) attack against
    the keypair generation pages:
    - HORIZON_URL/project/key_pairs/PAIRNAME/generate/
    - HORIZON_URL/project/key_pairs/PAIRNAME/download/
    These pages exposed creating and/or overwriting a keypair with a given
    name via a CSRF attack.
    
    This patch closes these holes by using only POST-based keypair creation,
    and exposing the keypair in the contents of a modal dialog instead of a
    download, which ultimately requires a GET.  It uses the same client-side
    features for both the Launch Instance keypair creation and Compute / Key
    Pairs panel.

Title:
  Generate and download keypair GET endpoint allows CSRF attacks

Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in OpenStack Security Advisory:
  Won't Fix

Bug description:
  Requests to create (and download) nova keypairs are made as GETs. As
  such the CSRF token is not sent nor validated on these requests. This
  breaks the principle Django's CSRF middleware relies upon which is
  that requests with side effects should not cause side effects. I'm
  told there was a reason for doing this related to being able to send
  the data back to the browser, and that this may not be trivial to fix.

  Filing this as a security bug since a malicious site could fool a user
  into creating keypairs. The attacker would not gain access to the
  contents, so the impact is not as serious as it might seem at first
  glance.
