cml_lab_facts module does not have fallback to ENV var CML_LAB

[tvarohohlavy]

There is an inconsistency between modules regarding the CML_LAB environmental variable usage.

cml_lab_facts does not have fallback to this ENV var:

ansible-cml/plugins/modules/cml_lab_facts.py

Line 71 in 716c622

argument_spec.update(lab=dict(type='str', required=True), )

but others do have it:

ansible-cml/plugins/modules/cml_lab.py

Line 117 in 716c622

lab=dict(type='str', required=True, fallback=(env_fallback, ['CML_LAB'])),

ansible-cml/plugins/modules/cml_node.py

Line 127 in 716c622

lab=dict(type='str', required=True, fallback=(env_fallback, ['CML_LAB'])),

It would make sense to have the same behavior when using ENV vars across all modules.
