Please decouple igbinary from php memcached package

[centminmod]

If one wants to install php memcached yum package on CentOS7 but doesn't want php igbinary, they can't due to dependency issues. Maybe have a separate lsphpXX-pecl-memcached-igbinary package for such and leave lsphpXX-pecl-memcached package without igbinary ?

same with lsphpXX-pecl-redis

Error: Package: lsphp56-pecl-redis-2.2.7-1.el7.centos.x86_64 (litespeed)
           Requires: lsphp56-pecl-igbinary(x86-64)
Error: Package: lsphp56-pecl-memcached-5.6.24-2.el7.centos.x86_64 (litespeed-update)
           Requires: lsphp56-pecl-igbinary(x86-64)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
An error occured during openlitespeed installation.
