Implement proper MS-CHAPv2 authentication for MikroTik PPPoE

Browse Source 
Two-processor approach:
1. MSCHAPv2GetPassword: Uses *authorize + *attributes to fetch password
   from CGRateS attributes subsystem and get MaxUsage for session timeout
2. MSCHAPv2Auth: Uses *radauth + *mschapv2 to perform actual MS-CHAPv2
   authentication with cryptographic proof (MS-CHAP2-Success)

The password is read from ~*cgrep.Attributes.Password (set via Attributes.csv)
and placed in *vars.UserPassword for the *radauth to use.
