Rename from slave to agent was reported in https://bugs.launchpad.net/magnum/+bug/1516188.
Following Patch fixed the above bug: https://review.openstack.org/#/c/338680/
But above patch break the mesos services. Some instances are:
1. service mesos-agent doesn't exist:
-----------------------------------------------------------
ubuntu@me-xdpwyptk57-0-m5cydvkjf7k5-mesos-agent-syfrrerpd6ir:~$ sudo service mesos-agent status
mesos-agent: unrecognized service
ubuntu@me-xdpwyptk57-0-m5cydvkjf7k5-mesos-agent-syfrrerpd6ir:~$ sudo service mesos-slave status
mesos-slave start/running, process 2789
------------------------------------
2. mesos monitor(/state) looks for agents, but "slaves" is present, output is below:

---------------------------------------------------------
3. Also, configuration is also not updated because configurations are pushed in "/etc/mesos-agent", but this directory doesn't exist instead "/etc/mesos-slave" exist
So, revert of https://review.openstack.org/#/c/338680/ is required until complete conversion of slave to agent is done.
Even then, ubuntu mesos image(ubuntu-14.04.3-mesos-0.25.0.qcow2) has to be updated because package installation is done in the image itself.
Fix proposed to branch: master
