[JUJU-1984] Update facade schemas for juju 3.0-rc1-2

[cderici]

Description

This PR updates the facade schema with the latest juju head (develop) and rebuilds the clients etc. This is mostly internal change to bring the libjuju up to date with the most recent changes in juju.

Just as a reference for the future, I'll note here all the versions that are bumped and started to be supported by libjuju:

Application : 15
Charms : 5
Client : 6
MachineManager : 8, 9
Resources : 3
SSHClient : 4
Subnets : 5
AllWatcher : 3
AllModelWatcher : 4

Two new facades are added:

CAASFirewallerSidecar
SecretsTriggerWatcher

QA Steps

Bootstrap with the latest juju on lxd or microk8s and try to run:

application = await model.deploy(
            'parca-k8s,
            application_name='parca',
            trust=True,
            channel='edge',
        )

All (except the known intermittently failing) CI tests need to pass. (The juju latest edge test is failing for some reason, though it's about the jenkins job, not juju/libjuju)

Notes & Discussion

Note that, this only changes the clients for the 3.0 track. The "old" clients, the ones we keep for the 2.9 track are untouched, and it should work the same.

Maybe @jnsgruk can help QA this too, as this change should fix this on parca.

I can confirm that parca-k8s can be deployed with these changes.
