This is just an FYI that I have proposed that we deprecate the 
core/ram/disk filters [1]. We should have probably done this back in 
Pike when we removed them from the default enabled_filters list and also 
deprecated the CachingScheduler, which is the only in-tree scheduler 
driver that benefits from enabling these filters. With the 
heal_allocations CLI, added in Rocky, we can probably drop the 
CachingScheduler in Stein so the pieces are falling into place. As we 
saw in a recent bug [2], having these enabled in Stein now causes 
blatantly incorrect filtering on ironic nodes.

Comments are welcome here, the review, or in IRC.
