Feature idea summary

Cgroups plugin supports only proportional and max Block IO policies. We should support BFQ scheduler as well. Disk stats for the scheduler are in blkio.bfq.io_service_bytes and blkio.bfq.io_serviced files.

Is your feature request related to a problem? Please describe.
With the yaml based config and options inherited from cortex etc its easy to make mistakes in the loki config file that don't manifest until runtime. Right now the only way to test the config, per the team on Slack, is to run loki on it. This is fine for a manual check but it becomes difficult to work with in CI environments.

Cloudprober supports building additional metrics (other than the default ones) from external probe output. We could possible do the same for HTTP probe.

What would you like to be added:
TM shows nicely, when a new update is available. Would it be possible to also show the version of the update?

Why is this needed:
Currently you have to go to the car to see the SW version, which is up to installing.

Of course a question, whether the API provides that information...
