[ovs-dev] [PATCH] xenserver: Add emergency_reset hook to XAPI plugin

There's a requirement that OVS can be put back into a known good state
remotely.  This will be implemented as a function through the OVS XAPI
plugin.  This commit only provides a hook for testing purposes.  The
functionality will be added later.
