Add TLS client events, server probing, and srv cert matching
This allows external programs (e.g., UI) to get more information

instead of the full certificate chain for cases where a trusted CA is

events and then adding a network configuration with the server
certificate hash after user have accepted it. Future connections will
then be allowed as long as the same server certificate is used.
