turris-diagnostic: localization added
This should add a localization for shell command turris-diagnostics.
Details should be described here: https://gitlab.labs.nic.cz/turris/diagnostics/tree/master#localization
Note that currently there are no translations, but you can edit and test it. On my debian it works quite well.
The goal of this effort is to display localized info for each diagnostic module in (re)foris.
