Subject: [PATCH] logs/traces: Initialize metrics to zero values

This commit ensures we treat logsv1 and tracesv1 group endpoints the
same as we do for metricsv1, when it comes to initializing metrcs.

As this API layer is usually used for tracking SLOs, absent alerts need
to be placed on some of the exposed metrics. This is a way to get around
those alerts firing on minimal traffic.
