exporters/prometheusremotewrite: Do not append '_total' to counter metric names #2993

This appears to have been enforcing convention but isn't actually required.

Description: The prometheusremotewriteexporter no longer appends "_total" to the name of counter metrics that don't already end in "_total". This was exposed by the PRW conformance test suite and this change partially addresses open-telemetry/prometheus-interoperability-spec#43.
