dellemc.powermax 4.0.0 with PyU4V 9.2.1.7 - we can't create MV

The starting_lun_adddress parameter was only added to the API in version 10.1 of the API this is documented in the change log and I called this out in blog post here.

https://infohub.delltechnologies.com/en-us/p/resting-on-our-laurels-what-s-new-with-the-powermax-api-and-unisphere-10-1/#:~:text=The%20provisioning%20API%20calls%20include,LUN%20Address%20when%20adding%20volumes.%20.

If this was in the API we could easily patch 9.2 version of PyU4V however the base API calls don't support it.  

Best thing to do in this case is if you are using older version of PyU4V is to avoid passing this parameter.  If you are mixing execution environments but need want to use this parameter where supported you could make it optional e.g. 

- name: Get PyU4V version
  shell: "python3 -c 'import PyU4V; print(PyU4V.__version__)'"
  register: pyu4v_version_result
  changed_when: false
  failed_when: pyu4v_version_result.rc != 0

- name: Set PyU4V version fact
  set_fact:
    pyu4v_version: "{{ pyu4v_version_result.stdout }}"

- name: Create MV with hostgroup (conditionally include starting_lun_address)
