Get flow settings api method for JSON-RPC V2 plugins

[cibere]

Is your feature request related to a problem? Please describe.

The only way for JSON-RPC plugins to get flow launcher settings is by reading the json files, which doesn't seem like a good UI.

Describe the solution you'd like

A getFlowSettings method to get all of these settings (like proxy settings, version, etc)

Describe alternatives you've considered

Reading the .json file(s) directly

Good suggestion, the only thing I'm not sure is if to expose all settings or only certain ones one by one.
