telegraf multi tags type

[jeonsoh]

Relevant telegraf.conf:

[[inputs.cpu]]
  percpu = true
  totalcpu = true
  collect_cpu_time = false
  report_active = false
  [inputs.cpu.tags]
    rule_id_1 = "1"
[[inputs.cpu]]
  percpu = true
  totalcpu = true
  collect_cpu_time = false
  report_active = false
  [inputs.cpu.tags]
    rule_id_1 = 2

System info:

telegraf-1.11.0
macOS 10.14.3

Steps to reproduce:

1. add multi tags in telegraf config file.
2. when I input the number type value 2 as a tag rule_id_1, It is not working well.
   it have to be below.

[inputs.cpu.tags]
    rule_id_1 = "2"

Expected behavior:

When I input the number type value as a tag, It have to work well, or I have to find out this at the guide

Actual behavior:

the tag rule_id_1 = 2 is not working.
And rule_id_1 = "1" is working well.

Additional info:

about multi tags -> https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md#input-plugins

Is it your intended behavior? or a bug?
if the latter is true, Could I try to fix?

Took a quick look and I think #7751 will take care of reporting this error.
