Conflicting tags

Hi Guys,
I think this is somehing wich was the case in #662

Bug report

I tried add tags to second SNMP Instance with different value and I get this

017/11/03 16:02:22 I! Using config file: /etc/telegraf/telegraf.conf
2017/11/03 16:02:22 E! Error parsing /etc/telegraf/telegraf.d/dc_doors.conf, toml: line 26: key `sensor' is in conflict with line 19

Relevant telegraf.conf:

[[inputs.snmp]]
  agents = [ "212.158.128.154:40160" ]
  timeout = "5s"
  retries = 3
  version = 1
  community = "public"
  name = "Doors"

  [[inputs.snmp.field]]
    name = "value"
    oid = "SNMPv2-SMI::enterprises.21796.3.3.1.1.4.1"
    conversion = "int"
    [inputs.snmp.tags]
      sensor = "door_1"

  [[inputs.snmp.field]]
    name = "value"
    oid = "SNMPv2-SMI::enterprises.21796.3.3.1.1.4.2"
    conversion = "int"
    [inputs.snmp.tags]
      sensor = "door_2"

System info:

Debian Wheezy
Telegraf version 1.4.3-1

Expected behavior:

I was expected that I will have measurement called Doors with value and different tags.
I have many of these sensors so it must be tagged to know which sensor is which.

[[inputs.snmp.field]] adds a field. [inputs.snmp.tags] has to go in an [[inputs.snmp]] section. You can't apply a tag to a field.
If you want to create multiple series, your options are to either set up an SNMP table (using [[inputs.snmp.table]], or define multiple [[inputs.snmp]] sections.

Thank you, I'd love to use snmp.table but sadly it's proprietary sensors solution and I cant use it. I define it separately. Thank you.
