Thanks [~abellina],
I merged this into master and 1.x-branch, but the cherry-pick was not clean
going to 1.0.x-branch so I didn't pull it in there. If you feel up to making a
similar change for that branch it would be awesome.

> In nimbus.clj there is some code to work around a race condition in
> compute-new-scheduler-assignments and read-all-supervisor-details. However,
> the race can be avoiding, hence removing the need for the workaround.
> This was exposed because RAS code is expecting the SchedulerDetail object to
> contain a resources map, but when the race happens these objects have that
> map set to null.
