bitmap-fonts does not exist on Amazon Linux
Add needed command to get graphite-web started when SE-Linux is enabled
Deleted the static port assignments

ports, just override the defaults attibutes in a role instead. Keeps

Bugfixing the changes needed to enable multiple caches on the same node
Fixed apparent typo
Keep things in sync

Question about this one if these values are actually needed for the
relay? They are (the UDP settings) not in the vanilla carbon.conf
