Sergei Golubchik 853bdf576f auto-disable --ssl-verify-server-cert in clients, if
* --ssl-verify-server-cert was not enabled explicitly, and
* CA was not specified, and
* fingerprint was not specified, and
* protocol is TCP, and
* no password was provided

insecure passwordless logins are common in test environment, let's
not break them. practically, it hardly makes sense to have strong
MitM protection if an attacker can simply login without a password.

Covers mariadb, mariadb-admin, mariadb-binlog, mariadb-dump
