MoleculeScenario doesn't support MOLECULE_OPTS

[evgeni]

When using the simple molecule_scenario fixture, that generates MoleculeScenario entries, there is no way to pass --parallel or similar flags via MOLECULE_OPTS

Looking at the code MoleculeItem does support that:

pytest-ansible/src/pytest_ansible/molecule.py

Lines 208 to 212 in 485c228

	# We append the additional options to molecule call, allowing user to
	# control how molecule is called by pytest-molecule
	opts = os.environ.get("MOLECULE_OPTS")
	if opts:
	cmd.extend(shlex.split(opts))

But that is not used in MoleculeScenario :(

@evgeni - I think you can set the MOLECULE_PARALLEL environment variable when running pytest, as per test subcommand. For example,

MOLECULE_PARALLEL=True pytest -k "your scenario's name"

However, you can't send --destroy=never because there is no support for MOLECULE_OPTS, so the issue is still valid
