Review request for mesos, Gastón Kleiman and Greg Mann.

Bugs: MESOS-9434

Repository: mesos


After a framework was removed and has unacknowledged operations status
updates, it was impossible to remove terminal operations as nobody could
acknowledge them.

In this patch we make the master acknowledge operation status updates
for frameworks it knows are removed so that e.g., terminal operations
can be removed. Since masters do not persist completed frameworks this
is not reliable (e.g., an agent was partitioned for a long time and
still tracks a completed framework's `FrameworkInfo`, and comes back
only after the master knowing about the framework's completion has
failed over). We merely extend the existing master behavior (e.g., send
`ShutdownFrameworkMessage` to all currently registered agents) to


  src/master/master.cpp b4faf2b077a0288ba36195b7a21402932489d316 
  src/tests/master_tests.cpp 51fcbe8d72fce1e56790d22ab7deced4fdb3bf0e 



* `make check`
* tested on a number of configurations in internal CI
* ran added test in repetition, both with and without additional stress
