Previously we scheduled a worker to just some this but we were running
into performance issues when the build table was getting too large. So
now we've updated the code such that this column is updated immediately
and incremented/decremented by the correct amount whenever artifacts are
created or deleted.
We've also added the performance optimization that we do not update this
statistic if a project is deleted because it could result in many
updates for a project with many builds.
Two things at ones, as there was no clean way to seperate the commit and
give me feedback from the tests.
But the model Artifact is now JobArtifact, and the table does not have a
type anymore, but the metadata is now its own model:
Ci::JobArtifactMetadata.
This adds counters for build artifacts and LFS objects, and moves
the preexisting repository_size and commit_count from the projects
table into a new project_statistics table.
The counters are displayed in the administration area for projects
and groups, and also available through the API for admins (on */all)
and normal users (on */owned)
The statistics are updated through ProjectCacheWorker, which can now
do more granular updates with the new :statistics argument.
