pagekite: Move to using python3-augeas
Created by: SunilMohanAdapa
- Merge actions/pagekite_util.py into plinth/modules/pagekite/util.py.
- Rename plinth/modules/pagekite/util.py to utils.py.
- Add python-augeus as dependency.
- Move actions/util.py to plinth/action_utils.py and update services that use it.
- Rename _run() method to run() as it is being used publicly.
- Import the utils in a more conventional manner.
- Move all python2 bits to python3.
PS: I could not get custom services to work. I have verified that configuration is setup as expected though.
