* Add comment to config file on log_max_size option
Mostly to support let's encrypt. It requires to switch from native-tls and friends to rustls and friends, which perhap is a good thing per se, rustls looks more modern and for sure more Rusty.
Alternative would be manually convert pkcs12 certificates to pem, which requires openssl tools to be installed and make transparent integration whith let's encrypt much harder (this is out of the scope for now, perhaps in near future)
* Allow TLS for Wallet APIs
This PR adds an optional support of TLS for wallet APIs. Only PKCS12 format is supported, will address .pem support in next PR and provide some documentation.
