in provision.sh check for existence of network file before starting the provisioning

[Jean-Baptiste Lallement]

Running provision.sh on a local machine to reproduce the CI environment it fails with:

+ log 'SETTING UP WIFI'
++ date
+ echo = mardi 4 $'f\303\251vrier' 2014, 10:49:23 '(UTC-0500):' SETTING UP WIFI
= mardi 4 février 2014, 10:49:23 (UTC-0500): SETTING UP WIFI
+ phablet-network -n /home/ubuntu/magners-wifi
Network connection file "/home/ubuntu/magners-wifi" cannot be read

Expected behavior:
THe script should check for the existence of a network file before starting the provisioning and not crashing after the device has been flashed.

That's just a default location for historical reasons. If you'd like to put one in that path it will pick it up, but in general, you need to use the -n option to specify your network profile (from NetworkManager). This is just passed off to phablet-network for you.

[Jean-Baptiste Lallement (jibel)]

Could you at least update the doc to mention this option and a check for existence of the network file in the script so it doesn't fail after the device has been reflashed but print a message before starting the provisioning ?

Now that we have mega-stuff merged in production, I should be able to add a small patch with jibel's suggestions.
