Input/filter/output metrics still exposed after setting enable_metric: false

[shog]

Hi,

It looks like enable_metric setting is being ignored and metrics are always enabled for all input/filter/output plugins.

How to repro:

Config (any tested input/filter/outplut plugin behaves the same way):

input { beats { enable_metric => false } }

After restarting logstash curl -s 'http://127.0.0.1:9600/_node/stats?pretty'
