Adapt netbox to paas-app-charmer 1.3.1

[javierdelapuente]

Overview

Several minor tasks have been done in this PR:

• Update version of paas-app-charmer used to 1.3.1
  • Remove all customisations in charm.py.
    • netbox-rq is now a worker service.
    • cron is run as a scheduler
• Upgrade all libraries and get net libraries.
• Upgrade integrations tests and cloud init tutorial to use juju 3.5 and microk8s 1.31.
• Fix release github action.

For cron processes, output is redirected now to /proc/$(pgrep cron -U 0 -P 1)/fd/2, so it gets sent to loki. I could not find a cleaner way (/proc/1/fd/2 it an invalid symlink and /dev/pts/X is not always the same number, a machine sshing there could get another value).

The "readiness" check has been removed for now. The reason is that it is useless (the ingress relation does not update the endpoints with it).

Rationale

Module Changes

Library Changes
