What Does This Do

Uses a single temporary buffer to prepare message chunks at different nesting levels (resource / scope / metric)

First we chunk all data points for a given metric. Once the metric is complete we add the first part of the metric message and its chunked data points to the scoped chunks. Once the scope is complete we add the first part of the scoped metrics message and all its chunks (metric messages and data points) to the payload. Once all the metrics data has been chunked we add the enclosing resource metrics message to the start of the payload.

Motivation

Avoids need to use full protobuf library while keeping intermediate array creation to a minimum.

Contributor Checklist

Jira ticket: [PROJ-IDENT]

Note: Once your PR is ready to merge, add it to the merge queue by commenting /merge. /merge -c cancels the queue request. /merge -f --reason "reason" skips all merge queue checks; please use this judiciously, as some checks do not run at the PR-level. For more information, see this doc.

Avoid creating an extra array that alway copies in the canned resource;
77c6674 
instead just create a small prefix and re-use the resource chunk as-is
