Tagpass with a list doesn't trigger error and just matches everything

[knollet]

Use Case

People work sloppily and try to match metrics with a tagpass = ["mymarkertag"] when the correct version would be tagpass = { "markertag" = ["mymarkertag"] } or similar.
Telegraf doesn't error out, though, and processors and outputs still process and put out the affected metrics because no working tagpass means matching every metric.

But it also matches metrics it shouldn't match and those end up in databases where they shouldn't end up.

Expected behavior

Error out with a config syntax error because tagpass expects a dictionary

Actual behavior

No erroring out and just matching everything leading to metrics in places where they don't belong.
