Shift slow test related pytest hooks in lower level conftest.py (tard…

…is-sn#578) * Move slow test related methods to lower level conftest.py - They conflicted with astropy's test plugins which were imported as *. * Use session wide temp director to store plots. * Use remote_data marker on pytest_unconfigure. * Shift unpacking of integration tests config in pytest_configure. * Cosmetic change - remove unused imports from conftest.py * Add a check in pytest_unconfigure for integration tests.
