AmqpConnectionFactory initiating AMQPSSLConnection for amqps:// DSNs.
Since php-amqplib 3.7 that class is deprecated and will disappear in v4, so every TLS connect now raises an E_USER_DEPRECATED notice.

A change (not from me) was suggested in php-enqueue/amqp-lib #5 (opened in the wrong repo). If feasibile may can be adapted from there?
