Sample for using OkHTTP interceptor for RxKotlin and Retrofit

• Interceptor will add the token into preference once after login
• Interceptor try to run the request once using current token in the OKHttp builder class
• If failed, it'll intercept by calling TokenRefreshInterceptor.kt
• TokenRefreshInterceptor.kt will try again, if got 200 from API
  • It'll call the refresh API by appending refresh token from preference to refresh the token
• Then proceed to call original request in makeTokenRefreshCall
