* Optimizing a little the Juniper RPM poller part

I wanted to query only the required values but it is complicated to query a specific OID
as Cisco-SLA does because the owner and tag are hardcoded in ASCII decimal with strange values.
So I use the function snmp_walk which gets the whole OID values in text.
And I index the Juniper MIB (because we want multiple values). But I changed the DISMAN MIB
requests to get only what we want.
