Place Server Name or something to identify the Block for error in Telegraf.log

Opening a feature request kicks off a discussion.

Proposal:

Place Server Name or something to identify the Block for error in Telegraf.log

Current behavior:

message is :
2018-10-11T19:34:47Z E! Error in plugin [inputs.mongodb]: Unable to connect to MongoDB, no reachable servers

And we have many MONGODB and MYSQL conf file blocks that have single inputs with the same [inputs.mongodb] and server defined under each. We use One telegraf with parameter differing between each and have multiple [inputs.xxxxxxxx] in the config file so we can customize conf. parameters differently for easch Mysql, Mongo, Cassandra collection definition.

multiple [inputs.mongodb] or [inputs.cassandra] or [inputs.redis] or [inputs.xxxxxxxxx] etc etc.

Desired behavior:

2018-10-11T19:34:47Z E! Error in plugin [inputs.mongodb]: Unable to connect to MongoDB, no reachable servers to server : myserver.domainname.com ( for the server named in the conf file)

2018-10-11T19:34:47Z E! Error in plugin [inputs.mongodb]: Unable to connect to MongoDB, no reachable servers to server : configuration parameter line # 1278

Help identify which [inputs.xxxxxxxxxx] is throwing the error

else i have to comment out and comment back in, and restart telegraf just to find the server which cannot connect or has a bad password, etc.

Use case: [Why is this important (helps with prioritizing requests)]

Config line is an interesting way we could handle this, but we would have to pair it with the config path in the case of multiple directories.
