Review request for mesos, Bernd Mathiske and Marco Massenzio.


Changes
-------

Address comments and propose a solution on duplicated logic


Bugs: MESOS-3340
    https://issues.apache.org/jira/browse/MESOS-3340


Repository: mesos


Description
-------

Currently, it appears that re-defining a flag on the command-line that was 
already defined via a OS Env var (MESOS_*) causes the Master to fail with a not 
very helpful message.

For example, if one has MESOS_QUORUM defined, this happens:

    $ ./mesos-master --zk=zk://192.168.1.4/mesos --quorum=1 
--hostname=192.168.1.4 --ip=192.168.1.4
    Duplicate flag 'quorum' on command line

which is not very helpful.

Current solution is to throw error if any duplication; over-write may make user 
confused about the result.
