Add IPv6 capability for RHEL/CentOS

For gmond.conf, add same capability as for Debian systems.
Add send_metadata_interval at 300s to debian

Previously, the send_metadata_interval for gmond was set at 0 for
Debian based systems, and 300 for Red Hat based systems.  This change
synchronizes the setting such that Debian is now 300s as well.
