Change socket mode to UDP for mesh in Jenkinsfile

Change socket mode to UDP for mesh in Jenkinsfile

• Change binding mode to UDP in simpleclient.h if building for mesh
  This is a workaround for IOTCLT-1296

We could also consider modifying the .h-file to have this part;

#if MBED_CONF_APP_NETWORK_INTERFACE == MESH_LOWPAN_ND
NETWORK_STACK = M2MInterface::Nanostack_IPv6;
#elif MBED_CONF_APP_NETWORK_INTERFACE == MESH_THREAD
NETWORK_STACK = M2MInterface::Nanostack_IPv6;
#endif

applied also to the TCP vs UDP mode setting. Might be useful for others, too.

[SeppoTakalo]

Yes!
That would be better solution.

//Select binding mode: UDP or TCP -- note - Mesh networking is IPv6 UDP ONLY
#if MBED_CONF_APP_NETWORK_INTERFACE == MESH_LOWPAN_ND || MBED_CONF_APP_NETWORK_INTERFACE == MESH_THREAD
M2MInterface::BindingMode SOCKET_MODE = M2MInterface::UDP;
M2MInterface::NetworkStack NETWORK_STACK = M2MInterface::LwIP_IPv6;
#else
// WiFi or Ethernet supports both - TCP by default to avoid
// NAT problems, but UDP will also work - IF you configure
// your network right.
M2MInterface::BindingMode SOCKET_MODE = M2MInterface::TCP;
// Select network stack mode: IPv4 or IPv6 - Eth + Wifi can be either
// Remember to match the mbed_app.json with this choice
M2MInterface::NetworkStack NETWORK_STACK = M2MInterface::LwIP_IPv4;
#endif

I think we should resolve the IPv4/IPv6 issue as well...

I think this should resolve it: https://github.com/ARMmbed/mbed-os-example-client/pull/139/files

@SeppoTakalo @kimlep01 Ideally we could also handle the UDP vs. TCP via the mbed_app.json file, I don't think it's ideal one has to tweak the source files for configuration issues but I haven't figured out yet a way to do that.

Please see also this; #137

@jankii01 I just ran tests with latest binaries from master as #139 was merged and 6lowpan has SOCKET_MODE : TCP enabled again.
