##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
Using vmware_guest to deploy a new VM with 'version' parameter set to integer 14.
Return error 'int' object has no attribute 'lower'.
This is caused in line 1285:
"if temp_version.lower() == 'latest':"

    description:
    - Template or existing virtual machine used to create new virtual machine.
    - If this value is not set, virtual machine is created without using a template.
    - If the virtual machine already exists, this parameter will be ignored.
    - This parameter is case sensitive.
    - You can also specify template or VM UUID for identifying source. version_added 2.8. Use C(hw_product_uuid) from M(vmware_guest_facts) as UUID value.
    - From version 2.8 onwards, absolute path to virtual machine or template can be used.
