Determine Galaxy Side Commands to support galaxy plugins for data sources

Determine all of the Galaxy Side [commands](https://galaxy-integrations-python-api.readthedocs.io/en/latest/) to support galaxy plugins as a source of game data.

Sample when there is no client response back:
`
{"id":"0","jsonrpc":"2.0","method":"get_capabilities","params":{}}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
{"error":{"code":-32700,"message":"Parse error"},"id":null,"jsonrpc":"2.0"}
`
From a fresh reboot (already imported data) from the generic plugin.
