Merge pull request #1113 from james-garner-canonical/client-schema-1-remove-eol-schema

#1113

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
