Metrics parameter renamed for 2018-01-01 api

[lukasmrtvy]

Hello,
metrics parameter for 2018-01-01 api should be name metricnames
https://docs.microsoft.com/en-us/rest/api/monitor/Metrics/List#uri-parameters

Error:

code="BadRequest" message="Detected invalid query parameter for metric metric for apiVersion: 2018-01-01, should be metricnames"

It would be awesome if something like
metrics "ALL" exists -> query API for all available metrics
