[PERF] PromQL: Pass concrete types to promql functions (#16797)
Currently, the promql functions take the interface slice []parser.Value as an argument, which is being implemented by the conrete types Vector, Matrix etc. This PR replaces the interface with the concrete types, resulting in improved performance. The inspiration for this PR came from #16698 which does this for binops. I extended the idea to all promql functions Signed-off-by: darshanime <deathbullet@gmail.com> * pass single Matrix Signed-off-by: darshanime <deathbullet@gmail.com> --------- Signed-off-by: darshanime <deathbullet@gmail.com>
