Fixes discovery failures on enterprise network devices with many
interfaces and routing table entries.
Issue:
Discovery was failing with "too_many_oids - OID values map exceeds
1000 entries" on SNMPv3 devices. Enterprise routers/switches during
discovery can easily return 10k-50k OIDs from:
- 100+ interfaces with 20-30 OIDs each
- System info, routing tables, ARP tables, neighbor tables
- Various MIB objects
The original limit of 1,000 was too restrictive for real-world devices
while still being intended as DoS protection.
Changes:
- Increase @max_oid_values from 1,000 to 50,000
- Update test to generate 50,100 OIDs (exceeds new limit)
- Add comment explaining why limit is set to 50k
This maintains DoS protection (prevents multi-million OID attacks)
while accommodating realistic device discovery scenarios.
All tests passing (5578 tests, 0 failures).
