Bugs: MESOS-9962

Repository: mesos


Under certain conditions tasks which were previously `TASK_LOST` and
completed can reappear in non-terminal states, e.g., if the agent on
which they where running reconnect.

This patch adds garbage collection of such completed tasks so that users
do not see tasks twice when obtaining task information from the master
API. This change does not affect tasks status updates where we already
correctly reported a previously `TASK_LOST` state as superseded by e.g.,


  src/master/master.cpp 351823e69f14dbb5eb1ea2b108c42e93722f1eff 
  src/tests/master_tests.cpp 5486e23ce146eda9191e081a48c1f3fcb52a7569 



`make check`
