Once received job deletion event, it cleans the backoff records for that
job before enqueueing this job so that we can avoid a race condition
that the syncJob() may incorrect use stale backoff records for a newly created
job with same key.

The v1alpha3 version is still needed for DeviceTaintRule, but the rest of the
types and most structs became obsolete in v1.32 when we introduced v1beta1 and
bumped the storage version to v1beta1.
Removing them now simplifies adding new features because new fields don't need
to be added to these obsolete types. This could have been done already in 1.33,
but wasn't to minimize disrupting on-going work.
This moves the enabled/disabled test into the common test/integration/dra which
simplifies the code a bit and amortizes the cost of starting the apiserver
because several different tests can use the same instance, running in parallel.
While at it, setting the status via SSA also gets tested.
As soon as we have more than one test using the scheduler, we need some
coordination between tests. This is handled by a singleton which starts the
scheduler for the first user and stops it after the last one is gone.
To avoid having to pass around an additional parameter, the context is used to
access the singleton under the hood.
This enables proper scheduling tests. Most of them are probably better done in
scheduler_perf where the same test then can also be used for benchmarking and
creating objects is a bit better supported (from YAML, for example), but some
special cases (in particular, anything involving error injection) are better
done here.
DRA drivers must provide ResourceSlices using the v1beta2 API types.
The controller then converts under the hood to v1beta1 if needed, i.e.
drivers are compatible with Kubernetes 1.32 and Kubernetes 1.33, as
long as at least one beta API group is enabled.
Testing pivots from using v1beta1 as the main API to v1beta2, with only one
test case exercising v1beta1.
A user of the controller can register an error handler via the controller
options. For a kubelet plugin, the error handler is method in the interface
which must be implemented. This is a conscious choice to make DRA driver
developer aware that they should react intelligently to errors.
The controller will invoke that handler with all errors that it encounters
while syncing the desired set of slices. This includes validation errors from
the apiserver if the driver's slices are invalid. Dropped fields get reported
with a special DroppedFieldsError.
