Hi maintainer,

Thanks for the role. I've been using it for some time.

Last time, running Ansible 2.9.9 and timorunge/ansible-freeipa-client (version 0.2.2) I got:

TASK [timorunge.freeipa_client : Install FreeIPA client packages] *******************************************************************************
fatal: [my-hostname]: FAILED! => {"msg": "Version comparison: '<' not supported between instances of 'str' and 'int'"}

I'll send you soon a PR.
