Fix bug with keyed_group group name transformation

[AlanCoding]

SUMMARY

If I used the setting to transform group names, it throws an error if keyed_groups are used, and those go over some groups with transformed characters

ISSUE TYPE

• Bugfix Pull Request

COMPONENT NAME

inventory plugin constructible

ADDITIONAL INFORMATION

Reproduce with

ANSIBLE_TRANSFORM_INVALID_GROUP_CHARS=false ansible-inventory -i aws_ec2.yaml --list --export -vvv

Where you are using keyed groups like

plugin: aws_ec2
keyed_groups:
  - prefix: ""
    separator: ""
    key: placement.availability_zone
    parent_group: zones

you get errors like

 [WARNING]:  * Failed to parse /Users/alancoding/Documents/repos/ansible-inventory-file-examples/private/ec2/aws_ec2.yaml with auto plugin: us-east-2 is not a known group

  File "/Users/alancoding/Documents/repos/ansible/lib/ansible/inventory/manager.py", line 272, in parse_source

    self._add_hosts(hosts=groups[group], group=group, hostnames=hostnames)
  File "/Users/alancoding/Documents/repos/ansible/lib/ansible/plugins/inventory/aws_ec2.py", line 500, in _add_hosts
    self._add_host_to_keyed_groups(self.get_option('keyed_groups'), host, hostname, strict=strict)
  File "/Users/alancoding/Documents/repos/ansible/lib/ansible/plugins/inventory/__init__.py", line 424, in _add_host_to_keyed_groups
    self.inventory.add_child(gname, host)
  File "/Users/alancoding/Documents/repos/ansible/lib/ansible/inventory/data.py", line 270, in add_child
    raise AnsibleError("%s is not a known group" % group)

This makes it work again with the setting on that.
