[buildbucket] Add recipe info to build proto

Milo would like to provide a link to the recipe used for a build.
Record the recipe cipd package and recipe name, coming from cr-buildbucket.cfg
This info will end up in BQ available for analysis.

This does not provide the source code location (buildbucket doesn't have it
anyway), but we could attach source code info to the CIPD package instance.
Then Milo could load that.

Later we can also add requested/actual CIPD version.

[buildbucket] Populate recipe info

Add recipe-specific properties to the Build entity.
Later we may simplify this when buildbucket has less responsibilities.
