[merge-103]Cleanup experimental recorder to use result provider

The recorder used database result and computed rank instead of using the
result provider which is wrapper on database to provide rank.
Additionally records uncomputed segments as "Unknown" instead of
skipping, so we can know how many users do not meet requirements in the
metrics.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
