glusterfs logrotate config file overrides defaults in RHEL 6.6 and RHEL 7.1

Issue

• The glusterfs package as provided in RHEL 6.6 and RHEL 7.1 includes a logrotate configuration with improperly-scoped config directives which override logrotate global default settings
• This will result in keeping all logs for up to 52 weeks instead of the default 4, which could result in unexpected amounts of disk usage in the /var/log directory, possibly filling the filesystem
• The glusterfs package is a dependency of the qemu-kvm package, so this affects any system running as a KVM hypervisor
