more confidence.

This 1.46 release adds a new widget in the build page that
allows users to follow up overall testjobs progress and
accross environments.

The release also fixes a bug when metadata has list of lists.

* api: rest: add endpoint testjobs summary of a build
* core: templatetags: squad_notification: handle list of lists

This 1.45 release adds several features around testjobs.
The first is the ability to remove resubmitted testjobs
results via a project setting. Also, another setting has
the capacity of telling SQUAD to reset all build events
upon testjob resubmission and new job submission. This means
that build callbacks, email notifications and patch notifications
can be retriggered automatically.

* api: ci: atempt to fetch job as they are watched
* ci, core: allow resetting build events
* ci: models: delete results from resubmitted jobs
* core: migrations: add MetricThreshold to default squad auth group

* frontend: testjobs:
* disable job resubmission if already resubmitted
* hide cancel button if job is already fetched
* refactor test job controls buttons
* remove dead code

This 1.44 release adds a bit of adjustments to the metrics changes done
in the previous release, like support for fetchin all build metrics
via a specific endpoint.

* api: rest:
* add metrics endpoint to builds
* add note on forcing comparing unfinished builds
* filter metrics by build, environment, and metadata
* prefetch metadata for metrics endpoint
* core: models: fix typo in comment
* frontend:
