Implements filtering on metric values.

What we want is to:
get all devices where the latest associated device metric for specified key is matching the provided filter (greater or less than X)

The current query gives the latest device metric where the requirements are met, so if there are at least one metric report that match for a device, that device will be included in result, no matter the timestamp.

Queries the latest inserted record for given metrics key, and checks if it matches the filter.

Includes a simple little functionality for testing in browser, just add params like ?metric=cpu_temp&metric_operator=gt&metric_value=37.0 to devices URL.

oh, this has totally been under my radar! Don't think it's ready, will go through it now and mark as ready when done. Thanks @joshk and @nshoes for reminding me

@joshk I don't remember why there's no filters selectors added to the UI, did we wanna wait for the new UI? I could add them before merging this, or after if preferred.

I think it might be good to add it to the current UI, as the new UI is still a little bit away.
