Add a new HSDir protocol version that definitely doesn't have the 0.3.0.7 bug
In 0.3.0.8, we fixed a bug in v3 HSDirs that stopped services uploading descriptors. But instead of allocating a new protocol version (or excluding broken versions from the consensus), we added a Tor version 0.3.0.8 or later requirement for v3 onion services to use v3 HSDirs.
This makes it impossible for an alternate Tor implementation to be a v3 HSDir.
So we should allocate a new HSDir protocol version that definitely doesn't have the bug, and skip the 0.3.0.8 or later check for relays declaring that version.
