ansible sharing parameters between tasks - ansible

Question

This may be an elementary question. I am using the following Ansible modules and was wanting to streamline my playbooks by reducing duplicate lines/variables.
https://github.com/HewlettPackard/hpe3par_ansible_module
I see that each task references a module that is using the same connection parameters. The variables are already defined in a parameters file but is there a way to move parameters to be more global so it doesn't have to be repeated in each task.
My playbook:
---
- name: Create 3PAR host and volume
hosts: localhost
tasks:
- name: Load Storage System Vars
include_vars: 'properties/storage_system_properties.yml'
- name: Load Host Vars
include_vars: 'properties/host_properties.yml'
- name: Create Host "{{ host_name }}"
hpe3par_host:
storage_system_ip="{{ storage_system_ip }}"
storage_system_username="{{ storage_system_username }}"
storage_system_password="{{ storage_system_password }}"
state=present
host_name="{{ host_name }}"
host_persona="{{ host_persona }}"
host_domain="{{ host_domain }}"
host_iscsi_names="{{ host_iscsi_names }}"
- name: Create Volume "{{ volume_name }}"
hpe3par_volume:
storage_system_ip="{{ storage_system_ip }}"
storage_system_username="{{ storage_system_username }}"
storage_system_password="{{ storage_system_password }}"
state=present
volume_name="{{ volume_name }}"
cpg="{{ cpg }}"
size="{{ size }}"
- name: Create VLUN
hpe3par_vlun:
storage_system_ip="{{ storage_system_ip }}"
storage_system_username="{{ storage_system_username }}"
storage_system_password="{{ storage_system_password }}"
state=export_volume_to_host
volume_name="{{ volume_name }}"
host_name="{{ host_name }}"
Desired playbook.

An option would be to use include_tasks. See example below.
> cat tasks-001.yml
- debug: msg="{{ var_001 }}-{{ var_002 }}-{{ var_003 }}"
> cat test-19.yml
- hosts: localhost
gather_facts: no
vars:
var_001: "001"
var_002: "002"
var_003: "003"
tasks:
- include_tasks: tasks-001.yml
- include_tasks: tasks-001.yml
vars:
var_003: "444"
- include_tasks: tasks-001.yml
vars:
var_003: "555"
- include_tasks: tasks-001.yml
vars:
var_001: "111"
var_002: "222"
- include_tasks: tasks-001.yml
vars:
var_001: "111"
var_002: "222"
var_003: "333"
- include_tasks: tasks-001.yml
> ansible-playbook test-19.yml | grep msg
"msg": "001-002-003"
"msg": "001-002-444"
