use subtest for table units (pkg-scheduler-algorithm-priorities)

**What this PR does / why we need it**: Update scheduler's unit table tests to use subtest

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:

**Special notes for your reviewer**:
breaks up PR: https://github.com/kubernetes/kubernetes/pull/63281
/ref #63267

**Release note**:

```release-note
This PR will leverage subtests on the existing table tests for the scheduler units.
Some refactoring of error/status messages and functions to align with new approach.
