Second phase of update process must be able to run completely offline

[mehrdadfeller]

In version 0.17.2 if the pod has no Internet connection during the 2nd phase of update, the ubo-update.service fails and the device becomes unresponsive. This is due to the fact that service tries to access some online services which are not needed.

Below is an example of such failure:

@sassanh Can I test this on v1.0.0? I believe you have addressed it already but not sure if it is on v1.0.0 or later dev versions.

@mehrdadfeller No, I haven't worked on it yet. I will give it some priority.
