Restore min_bin_version marker functionality

Add pytest hooks to register and handle the min_bin_version marker:
- pytest_configure: registers the marker
- pytest_collection_modifyitems: skips tests based on Tarantool binary version
- get_tarantool_bin_version: caches the version from a temporary instance
