> We cache FileSystem instances based on URI scheme & authority, plus username.  Elsewhere
we compare URI schemes and authorities case-insensitively, but the cache is case-sensitive.
 In particular, the Cache.Key#equals() and Cache.Key#hashCode() should be made case-insensitive.
> This should not be a blocker, since the worst it causes is a few extra FileSystem instances
to be cached.
