Move metrics SDK checks into API

[ocelotl]

Opening an issue to track this with the intention of being able to merge #2297 into main.

Curious as to why this behavior is defined in the sdk and not the api? Shouldn't all implementations of counter.add not take in negative increments?

I do agree with moving these checks from the SDK into the API. I can take this issue, but before that, I think this has not been discussed much yet. Does anyone prefer we take another approach?

@ocelotl
I suggest we bring this up during the next SIG meeting. Feel free to add this issue to the list of topics.

From 1/11 meeting, we have decided to leave the checks in the metrics sdk.
