Bas Nijholt d412c42ca4 Store state file alongside config file
State is now stored at .compose-farm-state.yaml in the same
directory as the config file. This allows multiple compose-farm
setups with independent state.

State functions now require a Config parameter to locate the
state file via config.get_state_path().
