[DISCUSS] PIP-272 Add a `StateStoreConfig` to the `WorkerConfig`

[Pengcheng Jiang]

Dear Pulsar community,

I created a pip to make pulsar functions' `StateStoreProvider` configurable
with custom configurations: https://github.com/apache/pulsar/issues/20419

Any feedback and suggestions are welcome

Sincerely
Pengcheng Jiang
