EA4 support for SSH2

As a server administrator needing to use the SSH2 module for PHP, I would like to see cPanel offer SSH2 in EA4 and start maintaining this package including updates.

SSH2 is available in PECL but is broken on PHP 5.6 and PHP7 for SFTP connectivity:

Apparently due to some security fix:

https://bugs.php.net/bug.php?id=73192

Current stable version is 0.13 :

https://pecl.php.net/package/ssh2

I want .13-3 which includes the patch provided by the custom REMI repo:

https://rpms.remirepo.net/enterprise/7/php56/x86_64/php-pecl-ssh2-0.13-3.el7.remi.5.6.x86_64.rpm

For those reading, you can add intval($sftp) to work around the issue in .13 without the patched RPM.
