* Considering that
* 1. starting from PHP 7.2.0 tls:// will negotiate best TLS version;
* 2. pre PHP 7.2.0 tls:// is TLS 1.0 only.
* The following decisions have been made.
* 1. This library uses TLS 1.2 by default for pre PHP 7.2.0.
* 2. Starting from PHP 7.2.0 this library uses the TLS negotiation by PHP, which
* means TLS 1.2 if available, otherwise falls back to a lower TLS version.
* Related: https://github.com/php/php-src/pull/2518 and https://wiki.php.net/rfc/improved-tls-constants
