Pub-dev: Expose all three score components

[mit-mit]

In our new design, the package score has three components:

1. Points (aka Pub Points)
2. Popularity
3. Likes

We currently expose these via several APIs:

For likes: https://pub.dev/api/packages/pana/likes
For popularity: https://pub.dev/api/packages/pana/metrics?pretty
For points https://pub.dev/api/packages/pana/metrics?pretty & https://pub.dev/api/packages/pana/score

I suggest we expand the metrics and score APIs to have all three score components:

{
  "grantedPoints":60,
  "maxPoints":110,
  "popularityScore": 0.6633297696569151,
  "likes": 7,
  "lastUpdated":"2020-09-03T22:11:22.940284Z"
}

@isoos do we know roughly when this will be deployed?

We have a planned deploy today with traffic migration tomorrow.

@isoos any chance we can also expose this on /metrics as I had mentioned in https://github.com/dart-lang/pub-dev/issues/3996#issue-694875174 ? We have some internal tools that call /metrics to get it's various information, and would like to avoid a second call to /score just to get the the likes (it already has popularity and points).

[isoos]

It would be easy to add the output of /score to /metrics too, but I wouldn't add the likeCount to the ScoreCard object internally - it requires different caching (analysis is once-in-a-while and is cached for a longer time, vs. likes which can change any time and cached for shorter time).

Added in #4025, will be available in the next release.
