Add tizen-device unit

[e-khalilov]

Run:

devicehub tizen-device \
--serial 192.168.31.250:26101 \
--provider tizen-test \
--public-ip localhost \
--connect-app-dealer tcp://127.0.0.1:7112 \
--connect-dev-dealer tcp://127.0.0.1:7115 \
--connect-sub tcp://127.0.0.1:7114 \
--connect-push tcp://127.0.0.1:7116 \
--device-host 192.168.31.250 \
--device-port 26101 \
--connect-port 6969

Notes

• Tizen does not support multiple SDB client connections, so the local client must also access the device via proxy
  (Use --connect-port for sdb connection, see for details - tizen-device/plugins/sdb/connect.js)
• Unlike other devices, the Tizen device sends an event for registration (wire.DeviceIntroductionMessage)
  in the device unit, not in the provider, which made it possible not to implement the unit provider in this PR
