Use Github Action Caching to Speed Up Unit and Integration Tests

[gsheni]

Problem Description

• Our unit, integration, and minimum tests currently take a long time to complete.
  • Longest integration test - 16m 22s (3.12, windows-latest)
  • Longest unit test - 8m 31s (3.10, windows-latest)
  • Longest minimum test - 17m 10s (3.11, windows-latest)

Expected behavior

• We can cache our python dependencies to speed up our workflow.
• Specifically, we can cache for integration, unit, minimum, and lint workflows.
• The change would look something like this:

    - uses: actions/checkout@v4
    - name: Set up python ${{ matrix.python-version }}
      uses: actions/setup-python@v5
      with:
        python-version: ${{ matrix.python-version }}
        cache: 'pip'
        cache-dependency-path: "pyproject.toml"
    - uses: actions/cache@v3
      id: cache
      with:
        path: ${{ env.pythonLocation }}
        key: py-${{ matrix.python-version }}-tests-${{ hashFiles('pyproject.toml') }}-v02
    - name: Install all deps (if cache has changed)
      if: (steps.cache.outputs.cache-hit != 'true')
      run: |
        make install-all
    - name: Install all deps (if cache has not changed)
      if: (steps.cache.outputs.cache-hit == 'true')
      run:  |
        python -m pip install --no-dependencies .

Appears to be minimal gain with caching and we have a limit to how much we can cache for tests. Closing without merging since the investigation results do not warrant the addition.
