#### Description
This upgrades protobuf/pdata to
[v1.7.0](https://github.com/open-telemetry/opentelemetry-proto/releases/tag/v1.7.0).
Note: due to the move of the lookup tables, merging profiles required
more non-trivial work.
In order to facilitate this review, merging is therefore currently
disabled for profiles. We will bring it back in a separate PR.
Note: this needs its contrib counterpart before it can be moved out of
draft.
Depends on
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.
