Title:
  rootwrap default config has uppercase sections

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  If you are using devstack to deploy neutron, agent will fail to start:

  2013-06-28 15:26:53.004 29285 DEBUG quantum.agent.linux.utils [-]
  Command: ['/opt/stack/quantum/bin/quantum-rootwrap-xen-dom0', '/etc/quantum/rootwrap.conf', 'ip', '-o', 'link', 'show', 'xapi1']

  Trying to run the rootwrap command:

  stack@DevStackOSDomU:~/quantum$ /opt/stack/quantum/bin/quantum-rootwrap-xen-dom0 /etc/quantum/rootwrap.conf ip -o link show xapi1
  Traceback (most recent call last):
    File "/opt/stack/quantum/bin/quantum-rootwrap-xen-dom0", line 102, in run_command
      session = XenAPI.Session(url)
    File "/usr/local/lib/python2.7/dist-packages/XenAPI.py", line 114, in __init__
      verbose, allow_none)
    File "/usr/lib/python2.7/xmlrpclib.py", line 1549, in __init__
      raise IOError, "unsupported XML-RPC protocol"
  IOError: unsupported XML-RPC protocol

  Looking at the rootwrap config file, the problem becomes obvious:

  $ cat /etc/quantum/rootwrap.conf
  [DEFAULT]
  # List of directories to load filter definitions from (separated by ',').
  # These directories MUST all be only writeable by root !
  filters_path=/etc/quantum/rootwrap.d

  # List of directories to search executables in, in case filters do not
  # explicitely specify a full path (separated by ',')
  # If not specified, defaults to system PATH environment variable.
  # These directories MUST all be only writeable by root !
  exec_dirs=/sbin,/usr/sbin,/bin,/usr/bin

  [XENAPI]
  # XenAPI configuration is only required by the L2 agent if it is to
  # target a XenServer/XCP compute host's dom0.
  xenapi_connection_url=<None>
  xenapi_connection_username=root
  xenapi_connection_password=<None>

  [xenapi]
  xenapi_connection_password = stg
  xenapi_connection_username = root

  And the rootwrap is searching for the config with capital letters.
