Add implementation and version metadata to bridge extra-info.

Browse Source 
This patch adds two new keys to bridges' extra-info document:
"transport-version" and "transport-implementation".

These two new values always appear together (if one is missing, the
other one will be missing too) and is parsed from PT's STATUS
TYPE=version messages.

See: tpo/core/tor#11101.
