Description

Add a test for oid lookup using mibs provided by network device vendors such as Juniper and Cisco.

The test would download mibs from a vendor, then configure telegraf's mib parsing/lookup code to use them and verifies that lookups work for oids that have been reported to fail.

Research direction
Refer to the linked PR #10428 and its comment for context on failing OID lookups. Identify the existing MIB parsing code in the Telegraf codebase (likely in a plugin or library). Simulate downloading a small set of vendor MIBs (e.g., from Juniper or Cisco) and create a test that verifies OID resolution after parsing those MIBs.
