Deploy CentOS+RadosGW+HA

Essential detail is that Controllers have 24 cores. Because of this httpd spawns 25*24 threads and exceeds 1024 nproc limit which is in /etc/security/limits.d/90-nproc.conf

This bug is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=919793

We need to remove 90-nproc.conf file completely or change nproc value to at least 2048
