shill: OpenVPNDriver: Write a configuration file

Instead of passing configuration to OpenVPN using command line
options, write out a configuration file instead.  This config
file is owned by root created in a run directory that is not
readable by any other users.  Although OpenVPN drops privileges,
it reads its configuration before doing so.  The configuration
file is removed with the regular OpenVPNDriver cleanup process.

As a side effect of this, all added options in the OpenVPNDriver
and OpenVPNManagementServer now lose their "--" prefix.
