Review request for mesos and Benjamin Mahler.


Summary (updated)
-----------------

[device manager] checkpoint state on device manager state change


Repository: mesos


Description
-------

Currently we do not checkpoint the device access state of each cgroup
when the configure or reconfigure is called. Meaning that we have
no way of recovering a cgroup's device access state.

We will checkpoint state of the device manager whenever its state
is being changed to ensure that we can recover the most recent state
when necessary.

Changes: https://reviews.apache.org/r/75143/diff/2-3/


Testing
-------

In later patches of the stack, we were able to ensure that the state was 
persisted and was able to be recovered.


Thanks,

Jason Zhou
