V2 Resolved Schema

[jsuereth]

Ready for review

This modifies the resolved telemetry schema (and template values) to look like the V2 definition schema.

With this PR you can resolve into the new schema via a new flag to check how it looks, e.g.

weaver registry resolve --v2 > test.yaml

Here's a sample of the new layout:

attributes:
  - key: android.app.state
    type:
      ...
signals:
  metrics:
  - name: aspnetcore.authentication.authenticate.duration
    instrument: histogram
    unit: s
    ...
  spans:
  - type: aws.client
    ...
  events:
  - name: app.jank
    ...
  entities:
  - type: android
    ...
refinements:
  metrics:
  - id: ...refinement id...
    ...full metric definition...
  spans:
    - id: ...refinement id...
    ...full span definition...
  events:
    - id: ...refinement id...
    ...full event definition...

left some comments, but looks great overall!

Wow, it took me quite some time to go through all of this. Thanks for the massive refactoring of the semconv schema and everything that comes with it!

Sorry for the number of comments. A lot of them are just copy/paste issues or typos. There are probably only a handful that really concern the approach or the decisions made. Apologies in advance if some of these points or answers have already been discussed in the SIG meetings; I haven't been very present in those lately.

testing this out on semconv and checking against problems identified for v1 in open-telemetry/semantic-conventions#2469

Resolved schema v2 - https://gist.githubusercontent.com/lmolkova/34dc5c0b0f583ca80681af3c9334238d/raw/d5b1ce469f149c1586b277cf3fe0f5772a480b72/semconv_schema_v2_copy.yaml

works fine now !

[lmolkova]

I tested weaver registry resolve --v2 and it works. I'm in favor of merging it and following up

LGTM. Thanks!
