SNMP requires multiverse on ubuntu

Multiverse is not guaranteed to be enabled by our cookbooks. Simply adding it as an apt-repo resource makes apt-get complain about duplicate sources.list entries.

Talked to marcelo -- we don't necessarily need the mibs installed. Might be better to remove multiverse dependency.

SNMP itself is installable without multiverse, but mibs are licensed, so they are in multiverse.
