Provide both a host and guest profile

openshift-node-host and openshift-node-guest profiles are to be used
for bare metal and virtual machine installations respectively. The rpm
installation scripts determine which profile is most appropriate based
on the output of the 'tuned-adm recommend' command so the user should
not need to make a selection on their own.

A manpage has been created as well.

+.SH NAME
+tuned\-profiles\-openshift-node - description of profiles provided for OpenShift
+
+.SH DESCRIPTION
+These profiles are provided for OpenShift nodes. They provide performance
+optimizations for OpenShift Nodes running on either bare metal
+(openshift-node-host) or virtual machines (openshift-node-guest).
+
+.SH PROFILES
+The following profiles are provided:
+
+.TP
+.BI "openshift-node\-host"
+Profile optimized for OpenShift hosts (bare metal). It is based on throughput\-performance
+profile. It additionally increases SELinux AVC cache, PID limit and tunes
+netfilter connections tracking.
+
+.TP
+.BI "openshift-node\-guest"
+Profile optimized for virtual OpenShift guests. It is based on virtual\-guest
+profile. It additionally increases SELinux AVC cache, PID limit and tunes
+netfilter connections tracking.
