Adding retry logic for gatt connection for VD client

- There was an issue initially reported for LUX, that Gatt Client disconnects just after it connects
- Connection retry logic was added as a fix in the commit 25ef240cc9978fa5945a26e72a8e763c436960db
- Again the same issue was reported for TV
- So adding the same fix in VD client
