BMP Support in Telegraf

### Use Case

I would like to have a new input format specifically for BMP data that a Telegraf instance is collecting and outputing to Kafka or direct to database before being graphed. Usage with the already present output options.

### Expected behavior

I would expect the data to be streamed through the output to our destination just like our snmp, http, etc. inputs are doing.

### Actual behavior

Right now this protocol is not supported.

### Additional info

https://www.openbmp.org/

Start by reviewing the existing SNMP and HTTP input implementations and the output paths for Kafka and databases; the issue does not name files or tests. Define the BMP input scope and verify that collected data reaches the requested destinations using the existing output options.
