#17991 Per discussion with @hpidcock, update Juju 3.6 to use the just-released Pebble v1.16.0 ([changelog](https://github.com/canonical/pebble/releases/tag/v1.16.0)). Summary of main changes: * Improvements to how services with dependencies are started and stopped (using "lanes"), so that independent services are started in parallel, and dependent services start up serially. Error handling is also improved. Fix in canonical/pebble#437. * A fix for a tricky bug in pebble exec, so it doesn't lose output in interactive mode. Fix in canonical/pebble#466! prdesc Reduce the size of exec tasks by not storing the execSetup (which includes all environment variables) in state. This speeds up (and shrinks the data) when serialising state to disk during state.Unlock. Fix is in canonical/pebble#478. prdesc Ensure Pebble doesn't hang (with no error message) when the state file directory is read-only or otherwise inaccessible. Fix in canonical/pebble#481. * Re-implement warnings using notices. This was always the intention since the notices feature was added (it was designed as a superset of warnings), but we'd never gotten to it. Lots of nice code deletion in canonical/pebble#486. ## QA steps Deploy a K8s charm, like `snappass-test`, and ensure `pebble version --client` on the workload reports v1.16.0.
