Describe the issue you're reporting

This is a request to add some more non-default metrics to the SQL Server receiver. I want to add more metrics as a part of this change.

Perf counter metrics
Disk read IO/sec
Disk write IO/sec

Note: The disk IO/sec metrics can be one metric with a direction attribute to differentiate read vs. write

Wait stats metrics
wait_time_ms - Coming from sys.dm_os_wait_stats, will need an attribute of wait type whose value can be resource, queue, or external, according to documentation. Definition:

Total wait time for this wait type in milliseconds. This time is inclusive of signal_wait_time_ms.

We can use the telegraf query to get this wait metric.
