Bugs: MESOS-3351
    https://issues.apache.org/jira/browse/MESOS-3351


Repository: mesos


Description
-------

__Phenomenon:__
In some race condition, the slave was shutdown when after master failover.

__Root Cause:__
The slave was shutdown because of duplicated SlavID: in master, the SlaveID is 
genereated by masterInfo.id + "-S" + nextSlaveId; when master failover, 
nextSlaveId was reset to 0 and masterInfo.id (generated by date + ip + port + 
pid) maybe un-changed which lead to duplicated SlaveID. 

__Solution/Fix:__
Generate masterInfo.id by UUID instead of "date + ip + port + pid".
