> In production code, we only use [cache Context.SelectApplications|https://github.com/apache/yunikorn-k8shim/blob/2c502c01f7a116281d94efb250ac4184a371a06a/pkg/cache/context.go#LL928C2-L928C2] in [KubernetesShim.schedule|https://github.com/apache/yunikorn-k8shim/blob/2c502c01f7a116281d94efb250ac4184a371a06a/pkg/shim/scheduler.go#L279] with a {{nil}} filter.
> In testing code, [MockScheduler.waitAndAssertApplicationState|https://github.com/apache/yunikorn-k8shim/blob/2c502c01f7a116281d94efb250ac4184a371a06a/pkg/shim/scheduler_mock_test.go#L155-L157] and [MockScheduler.waitAndAssertTaskState|https://github.com/apache/yunikorn-k8shim/blob/2c502c01f7a116281d94efb250ac4184a371a06a/pkg/shim/scheduler_mock_test.go#L193] use it to filter apps by application ID, but this can be replaced by [cache Context.GetApplication|https://github.com/apache/yunikorn-k8shim/blob/2c502c01f7a116281d94efb250ac4184a371a06a/pkg/cache/context.go#L799].
> So we can use a new function {{{}GetAllApplications{}}}, and remove SelectApplications in the code base.
