https://github.com/open-telemetry/opentelemetry-collector/pull/12856Resolves#12676
This is a reboot of #11311, incorporating metrics defined in the
[component telemetry
RFC](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/component-universal-telemetry.md)
and attributes added in #12617.
The basic pattern is:
- When building any pipeline component which produces data, wrap the
"next consumer" with instrumentation to measure the number of items
being passed. This wrapped consumer is then passed into the constructor
of the component.
- When building any pipeline component which consumes data, wrap the
component itself. This wrapped consumer is saved onto the graph node so
that it can be retrieved during graph assembly.

This is the last functionality needed to replace
`metadatatest.Telemetry` with `componenttest.Telemetry`.
The `metadatatest.Telemetry` will be deprecated next release to give
time to change contrib since it is a large change.
