<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
vmware_guest
##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
ansible 2.10.0.dev0
  config file = None
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /root/ansible/lib/ansible

##### 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':"
<!--- Paste example playbooks or commands between quotes below -->
```yaml

```
