Squad

This 1.35 release fixes a small issue when viewing all test results in Build page

Complete list of changes going in:

* frontend: tests: improve performance loading all test results
* doc: document how callbacks work

This 1.34.1 release fixes Plugins notifications when the project has no
recipients subscribed to it or when there's a race condition.

The release also fixes a scenario where a TestJob might get canceled
before getting a job_id from the backend, therefore entering a limbo state
where it can't be resubmitted.

Complete list of changes going in:

* core: tasks: notification: prevent duplicate patch_source notification
* ci: lava: fix resubmit on testjobs with empty job_id
* core: notification: mark as notified even if no recipients available

This 1.34 release adds several nice features:

1. Social login: now users will be able to login using their Github or Gitlab accounts
2. New notification strategy (ON_ERROR)
3. Adds implementation of test confidence score, when tests are run
for the save build/suite/environment
4. Callbacks: for now only callbacks to finished builds are implemented
extending it should be simple though

Among other minor bug fixes and performance improvements.

Complete list of changes going in:

* api:
* add version endpoint
* rest/views: handle callback duplicates
* rest: create build callbacks via nested endpoint
* rest: enhance builds nested endpoint in projects endpoint
* rest: fix /api/projects/<id>/builds/
* rest: hide project_settings
* rest: use lighter version of TestComparison
* views: create callback for build via createbuild
* ci: listen: increase backend check poll to 1 min
* core:

This 1.33 release tweaks TestComparison making it much faster
when only regressions and fixes are needed. It brings these changes
through a single database query, instead of loading all tests in memory.

The release also saves precious time when fetching lots of builds and
tests from the API.

Last by not least, this release of SQUAD also comes with a new field
to Build called `patch_url` which stores the originator url of that build.

Complete list of changes going in:

* api: rest
* order tests by id instead of build_id
* remove leftover print statement
* squeeze in a few extra ms fetching builds
* squeeze in a few extra ms fetching tests
* core:
* comparison: fix regression detection
* comparison: fix regression detection
* comparison: use raw sql to get regressions and fixes
* frontend: Display URL from patch source
* models: use metadata for retrieving test full name
* docs: fix a typo in the api docs
* Dockerfile: freeze importlib-metadata version
* dev-docker: freeze importlib-metadata version
* test: core: avoid unnecessary project status update

This 1.32 release completely removes TestRun and Attachment file
fields, leaving it to be saved in storages only.

The release also tweaks the script that fixes buggy squadplugin
generated SuiteMetadata objects.

Complete list of changes going in

* core, commands: 4th attempt to make faster fix
* core: delete old storage fields for TestRun and Attachment

This 1.31 release adds a long-wanted feature in SQUAD which
is the ability of fetching Build's tests without having to
go through TestRun table. Some queries are going to be
optimized and large installations will feel the difference
almost right away.

This release also fills up all environment columns when checking
a test's history.

Complete list of changes going in:

* api: rest: add tests endpoint to build
* api: rest: add build, environment and metadata filters
* ci: backend: lava: handle HTTP 408 as TemporarySubmissionIssue
