Add LDAPClient.from_realm(), LDAPClient.from_hostname_secure(), and
LDAPClient.from_hostname_plain() constructors.
The simple_bind() method now also refuses to transmit a password over a
plain, unencrypted line.
LDAPClient.from_hostname_secure() uses start_tls and FreeIPA's CA cert
by default. The constructor also automatically disables start_tls for
ldaps and ldapi connections.
