o Minor bugfixes (onion services): - If we are launching repeated HSFETCH queries and are rate-limited, we introduce a new controller response QUERY_RATE_LIMITED instead of QUERY_NO_HSDIR, while keeping the latter for when onion service directories are missing a descriptor. Previously, we returned QUERY_NO_HSDIR for both cases. Fixes bug 28269; bugfix on 0.3.1.1-alpha. Patch by Neel Chauhan
