Since https://github.com/ansible/ansible/pull/56733, we were not able to apply
firewall rules with no `allowed_hosts` key.
closes: #61332
In addition, this patch ensures the `allowed_hosts` key accepts a dict,
instead of a dict in a single entry list.
```yaml
vmware_host_firewall_manager:
esxi_hostname: "{{ esxi1 }}"
rules:
- name: NFC
enabled: True
allowed_hosts:
- all_ip: False
ip_address:
- "1.2.3.4"
```
Should be written:
```yaml
vmware_host_firewall_manager:
esxi_hostname: "{{ esxi1 }}"
rules:
- name: NFC
enabled: True
allowed_hosts:
all_ip: False
ip_address:
- "1.2.3.4"
```
The use of the `hostvars[esxi1].ansible_host` was attempt to use
different hostname and IP address. But it's actually the source of
more problems.
VMware expects to be able to resolvable the host name. This means, that
if someone wants to run the test-suite, s/he needs to use a DNS or
update the `/etc/hosts` files on the different hosts.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
