MINOR: ssl/cli: support filters and options in add ssl crt-list

Add the support for filters and SSL options in the CLI command
"add ssl crt-list".

The feature was implemented by applying the same parser as the crt-list
file to the payload.

The new options are passed to the command as a payload with the same
format that is suppported by the crt-list file itself, so you can easily
copy a line from a file and push it via the CLI.

Example:
  printf "add ssl crt-list localhost.crt-list <<\necdsa.pem [verify none allow-0rtt] localhost !www.test1.com\n\n" | socat /tmp/sock1 -
