MEDIUM: ssl/cli: apply SSL configuration on SSL_CTX during commit

Apply the configuration of the ssl_bind_conf on the generated SSL_CTX.
It's a little bit hacky at the moment because the ssl_sock_prepare_ctx()
function was made for the configuration parsing, not for being using at
runtime. Only the 'verify' bind keyword seems to cause a file access so
we prevent it before calling the function.
