feat(client-only-schemas): remove schemas for EOL Juju 3.2

[james-garner-canonical]

Remove 3.2.X schemas. Delete _client*.py and run make client.

Description

Moving towards the goal of having schemas and generated code in python-libjuju only for the latest supported Juju versions (3.1.9, 3.3.6, 3.5.4, 3.5.3), and using client only schemas (see #1099), this PR removes schemas for EOL Juju 3.2, and reruns code generations, removing _client*.py files and then running make client.

QA Steps

CI steps should all continue to pass, except for integration testing which should continue to fail with the usual suspects (see #1108 for a non-exhaustive table of tests that sometimes fail on main).

Notes

To hopefully simplify the diffs, this is the first PR in a planned sequence of PRs that will depend on each other. Subsequent PRs will be:

1. replace current schemas with latest release client only schemas (3.1.9, 3.3.6) and regenerate code
2. add client only schema for 3.4.5 and regenerate code
3. add client only schema for 3.5.3 and regenerate code

given that _client18 get removed, I'm pretty sure these lines need to be updated:

juju/client/_client.py
26:from juju.client import _client7, _client1, _client3, _client4, _client2, _client17, _client6, _client11, _client10, _client5, _client9, _client18, _client19
41:    "18": _client18,

Funnily enough, _client12 was never imported in the first place 🚀

Actually, _client18 is the only one that wasn't removed, and was instead modified. So the imports are correct, which is a relief since they're from codegen.

Easy to miss that _client18 is still there in the Files changed tab as the diff is also hidden due to being too large.

Ah, so true!
