<!--- Verify first that your issue is not already reported on GitHub -->
<!--- Also test if the latest release and devel branch are affected too -->
<!--- Complete *all* sections as described, this form is processed automatically -->

##### SUMMARY
<!--- Explain the problem briefly below -->
Since commit df581eb ovirt_vm is unable to find a template shared among multiple clusters in the same datacenter. Moreover, the document says that `cluster` parameter is a parameter used to define where VMs will be created. Then it should not be used to filter a template search which is not related to VM storage.

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
ovirt_vm

##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
2.8.2
```

##### CONFIGURATION
<!--- Paste verbatim output from "ansible-config dump --only-changed" between quotes -->
```paste below

```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->


##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
In RHEVM:
1. Create a cluster `cluster_a` and add a template `template_a` in this cluster
2. Create a cluster `cluster_b`

<!--- Paste example playbooks or commands between quotes below -->
```yaml

- name: Provision machine
  ovirt_vm:
    ...
    cluster: "cluster_b"
    template: "template_a"
    ...
```

<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
The template should be found (Behaviour before commit df581eb)

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->
It raises an error

<!--- Paste verbatim command output between quotes -->
```paste below
Template with name 'template_a' and version 'None' in cluster 'cluster_b' was not found
```
