since we're allowing a nil @multi_cache object, setting it to nil not only means we don't
reload it, it means we completely ignore it and always fall back to Rails.cache

so that the default shard will use it as well
this also means MultiCache will load earlier, so move #cluster to Canvas
instead of ApplicationController to reduce how much is loaded. and don't
memoize the value of Rails.cache at that point, since it might not be
fully configured yet if you're not using ha_cache.yml

RedisStore is no longer supported
somewhat surprisingly, the serialization formats are compatible, so we don't

explicitly have one copy per node in a ring (instead of relying
on hashing of a different to hopefully evenly spread copies around
the ring).
test plan:
* configure a ring of redis servers for cache
* canvas should still work
