QNAP update (#6182)

* Bump qnapstats library to 0.2.3

* Expose the new timeout setting

* Show persistent notification if QNAP fails to set up

This sitaution will usually occur if the server configuration is wrong or the
timeout is set too low.  In both cases `api.update()` will fail, which is a
problem because we cannot initialize many of the sensors without having this
data.

* Add new system_temp condition to QNAP sensor
