Remove v0 hidden service statistics code.

The HSAuthorityRecordStats option was used to track statistics of overall
hidden service usage on the version 0 hidden service authorities. With the
version 2 hidden service directories being deployed and version 0
descriptors being phased out, these statistics are not as useful anymore.

Goodbye, you fine piece of software; my first major code contribution to
Tor.
