Tunnel: Cleanup old tunnel infrastructure.

Since userspace flow based tunneling code is checked in, the kernel
port based tunneling code can be removed.

Patch removes following components:
 - tunnel ports hash table and moved tunnel ports list to individual
   vports.
 - Cleaned per tnl-port config.
 - OVS_KEY_ATTR_TUN_ID action is removed.
