    Configuring number of apache processes
    
    By default apache spawns only one process for the wsgi app if not specified.
    This patch detects the number of CPUS to configure n CPUs +1 processes by
    default and allows to specify the number of processes explicitly.

Title:
  The generated apache configuration does not spawn enough processes and
  this can lead to a stalling server (potential DoS)

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  When creating the apache configuration with:

   python manage.py make_web_conf --apache

  The apache configuration file does not specify the number of apache processes.
  By default apache will spawn only one. not only is it a performance issue, but it can lead to Denial of Service if the apache process is to long to respond or stalled.
