checkrad patch to support Juniper's BRAS

[Guilherme Franco]

Hello,

I would like to submit a patch to checkrad (freeradius-server-2.1.12),
adding support for Juniper's E-Series BRAS (ERX, E120, E320).

It adds the possibility to query the subscriber's username using SNMP.
If the subscriber is found, it returns 1 "Returning 1 (double
detected)", else, returns 0 "Returning 0 (login ok)".

On clients.conf, the nastype should be set to juniper.
