This command is intended for "Network Devices Monitoring" users who need to enrich traps that are not automatically
supported by Datadog.
The expected workflow is as such:\n
1- Identify a type of device that is sending traps that Datadog does not already recognize.\n
2- Fetch all the MIBs that Datadog does not support.\n
3- Run `ddev meta snmp generate-traps-db -o ./output_dir/ /path/to/my/mib1 /path/to/my/mib2`\n
You'll need to install pysmi manually beforehand.
