[all] Removed BMC info that was manually added to cluster YAML files - scripted

done with:

nodes=$(find . -iname "*.yaml" | grep -v nodes)

for i in $nodes
do
    echo $i
    cat $i | tr '\n' '\r' | sed 's,[ ]*bmc:[^\r]*\r[ ]*ip:[^\r]*\r[ ]*mac:[^\r]*\r,,g' | tr '\r' '\n' > $i.tmp
    mv $i.tmp $i
done
