This PR removes a bunch of complexity that the Metrics SIG group decided not to specify for the default SDK. The implication is that you will no longer be able to convert asynchronous counters into delta counters for export, which is no great loss.

Fixes #2349.

LGTM, needs attention to get lint to pass.

Looks like this needs a make precommit to ensure gofmt has run on everything?

Gahh, I spoke too soon. I forgot that @bogdandrutu is not in the @open-telemetry/go-approvers group. We need one more approval.
