<!--- 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 -->
We are using the vmware_guest module to deploy a VM Template on a vCenter cluster. When we specify a virtual network name that contains a slash in it (e.g. 0123-network-name-10.0.0.0/22), Ansible returns "Network '0123-network-name-10.0.0.0/22' does not exist. This problem does not occur with network names that do not contain slashes.

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
<!--- 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 2.8.5
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/awx/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Oct  7 2019, 17:58:22) [GCC 8.2.1 20180905 (Red Hat 8.2.1-3)]
```

##### 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. -->
Ansible running within AWX 9.0.0
Target vCenter environment - vCenter 6.7.0 build 14070654

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
Create a playbook with a single task in it to deploy and customize a VMware Template using the vmware-guest module. Specify a virtual network name with a "/" in it.

<!--- Paste example playbooks or commands between quotes below -->
```yaml
- name:  Clone a virtual machine from Linux template and customize
  vmware_guest:
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_user }}"
    password: "{{ vcenter_password }}"
    validate_certs: no
    datacenter: "{{ datacenter }}"
    state: present
    folder: "{{ vm_folder }}"
    template: "{{ template }}"
    name: "{{ vm_name }}"
    cluster: "{{ vm_cluster }}"
    networks:
      - name: "{{ vm_network }}"
        dvswitch_name: "dvSwitch"
    hardware:
      num_cpus: "{{ vm_hw_cpus }}"
      memory_mb: "{{ vm_hw_mem }}"
    wait_for_ip_address: True
    customization_spec: "{{ vm_custspec }}"
  delegate_to: localhost
```

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
Expect vmware_guest to launch or update the VM specified by vm_name variable with the parameters specified.

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