Raise a FATAL error if the user tried to combine v2 and prop224 hidden service in same directory

A user is hosting a hidden service:

Hid /path/to/key/hs-www/ hidport 127.0.0.1:80 80

What will happen if he add "HidVersion V3" line to the middle of the config?

Hid /path/to/key/hs-www/ HidVersion V3 hidport 127.0.0.1:80 80

Tor should detect this misconfiguration and raise an error. (v2 and v3 keys should not exist in same directory)

should be;

Hid /path/to/key/hs-www/ hidport 127.0.0.1:80 80

Hid /path/to/key/hs-www-v3/ HidVersion V3 hidport 127.0.0.1:80 80
