Add support for Octavia Amphore V2
For backward compatibility the default driver still Amphore v1.
One can use Amphore V2 as driver, by specify
`config.octavia.api_settings.default_provider_driver`
`config.octavia.api_settings.enabled_provider_drivers`
Also for authentication, you can provide
`.Values.endpoints.valkey.password` to use password auth, but more
recommanded way is to use CA cert access.
And then add path to
`config.octavia.task_flow.jobboard_redis_backend_ssl_options` and
`config.octavia.task_flow.jobboard_redis_sentinel_ssl_options`.
