We need to find out is it possible to run several C* nodes on the same mesos slave. Please refer to http://www.datastax.com/dev/blog/running-multiple-datastax-enterprise-nodes-in-a-single-host

It is possible, but we need several nics/ips on slave node, becase C* forces us to use the same internal (storage) port. Implemented basic version. Now it is possible to:

specify several of --bind-address for cluster (./dse-mesos.sh cluster update default --bind-address=if:eth1,if:eth2)
run several C* on the same slave;

Limitation: dse agent port is not dinamically reserved. Still need better dse agent support, but that's in the separate ticket.
