Note the timestamp difference between the agent settings and snmp_trap finally saying it is listening.

System info

telegraf 1.21.3 + master

Steps to reproduce

1. Configure snmp_trap input with a directory with lots of MIBs
2. Start telegraf

Expected behavior

Telegraf to load files quickly and start listening on port immediately.

Actual behavior

Telegraf seems to hang in input initialization with lots of files/big files/malformed files. Does it also appear to read them multiple times?
