[Juju 3.6] Restrict supported series by what controller actually supports #1172

Open dimaqq opened 3 hours ago

Description

ResolveCharms returns:

{'request-id': 9, 'response': {'Results': [
{'url': 'ch:amd64/ubuntu-25', 'charm-origin':
 {'source': 'charm-hub', 'type': 'charm', 'id': '', 'risk': 'stable', 'revision': 25, 'track': 'latest',
  'architecture': 'amd64', 'base': {'name': 'ubuntu', 'channel': '22.04/stable'}},
  'supported-series': [
        'jammy',
        'focal',
        'bionic',
        'xenial',
        'trusty',
        'precise',
        'groovy',
        'disco',
        'cosmic',
        'artful',
        'vivid'
]}]}}

However, controller will reject an attempt to deploy on vivid.

Likewise, if the client always picked the newest (charmhub) base and ran against older Juju, client could ask for jammy that is not yet supported.

It's not an issue for older Jujus today, because older Juju returns 'ch:amd64/jammy/ubuntu-25' directly indicating the (preferred?) base.
