Merge pull request #4791 from RosettaCommons/vmullig/rename_within_HierarchicalHybridJDApplication
Replace "emperor"/"master"/"slave" within HierarchicalHybridJDApplication, which some people found objectionable.
I'm still not a fan of making an major effort to avoid _analogies_ to slavery when the tech industry and the University of Washington still make use of _actual_ slavery in the form of forced prison labour (i.e. I think we're just making institutions look virtuous that don't deserve to be made to look virtuous, which engage in a practice that's banned in most developed nations), but maybe once we've made this code change we can talk about something more concrete that we can do that actually helps to close the 13th Amendment loophole and to end slavery in the U.S.
TODO:
- [x] Change "emperor"/"master"/"slave" to "director"/"manager"/"worker".
- [x] Carefully check the integration tests. (Everything will change, but make sure nothing breaks.)
- [x] Update documentation --> see RosettaCommons/documentation#42
- [x] Check scientific tests --> they failed.
- [x] Update scientific tests.
- [x] Re-check scientific tests --> they passed.
- [x] Update `threads_per_slave` option.
- [x] Beauty.
- [x] Note that pull request #4761 must be merged before this one.
