Refactor integration tests

Integration tests are in ./test and may need external data or services.

For example one that needs external data

def test_getListFineSlicedReferenceImagePath(self):
    beamline = "id30a1"
    strategy_result = edna_mxv1.create_n_images_data_collect(
        exposureTime=1.0,
        transmission=100,
        number_of_images=1,
        osc_range=0.1,
        phi=123.0,
    )
    directory = (
        "/data/id30a1/inhouse/opid30a1/20220408/RAW_DATA/Sample-8-1-01/MXPressA_01"
    )
    run_number = 1
    exp_type_prefix = "ref-fineslice-"
    prefix = "opid30a1"
    suffix = "cbf"
    tmpdir = tempfile.mkdtemp()
    edna_mxv1.getListFineSlicedReferenceImagePath(
        beamline=beamline,
        mxv1StrategyResult=strategy_result,
        directory=directory,
        run_number=run_number,
        expTypePrefix=exp_type_prefix,
        prefix=prefix,
        suffix=suffix,
        dest_dir=tmpdir,
    )

Refactor

• rename ./src/bes/test to ./src/bes/tests
• modify tests in ./test to use pytest and move to ./src/bes/tests
• use pytest.skip when the external resource is not available
• copy external data to /data/scisoft/bes_testdata
