SINGA-201 Error when running Mesos

A bug was reported (https://issues.apache.org/jira/browse/SINGA-201) when
launching SINGA on Mesos in fully distributed mode.

The main cause was determined to be of ZeroMQ binding to the localhost. In fully
distributed mode, SINGA on each node should be passed a `-host` flag specifying
the public IP address of the local host.

The Mesos scheduler is modified accordingly:

1. When a Mesos slave starts connecting to the master, it passes `--hostname` flag specifying its public IP address

2. The scheduler now sends to each executor command of the form:

          `singa -conf ./job.conf -singa_conf ./singa.conf -singa_job XX -host XX`
