config improvements #628
Description
- we should return an error if a config element is unknown (rather than ignore it)
- add some new elements to the p2p config (commands, config: tally and report unknown fields in config #636):
- max_msg_packet_payload_size
- send_rate
- recv_rate
- we should add some function, eg.
config.Parse()to check the validity of all arguments. Ie that ints are positive, that strings are from the allowed set, etc. - separate config files and data by creating 2 subfolders (config, data) (separate config files and data by creating 2 subfolders (config, data) #556, config: split data and config directories #709)
- config docs (config docs #705, write config.toml with all defaults & improve config doc #733)
