promtool check-rules should alert on duplicates

[momorientes]

What did you do?
Duplicate Recording Rules(out of stupidity):

ifInRate{} = (rate(ifInOctets[1m])*8) / ifSpeed
ifInRate{} = (rate(ifOutOctets[1m])*8) / ifSpeed

What did you expect to see?
a warning of some kind when running promtool check-rules

What did you see instead? Under which circumstances?

WARN[8657] Error on ingesting results from rule evaluation with different value but same timestamp  numDropped=77 source=manager.go:299

This is potentially a valid setup, there's no general way to detect this sort of thing.

Indeed nothing that indicates an actual issue. We don't want to get into the business of warnings as that will be quite a rabbit hole.
