When forwarders list or the no_forwarders flag has been set, the
configuraiton does not reflect the setting. With no_forwarders
the preparation step of the DNS server could fail in ipaserver_prepare.
This is addressing the issue of pull request #25.
A new section has been added to configure firewalld automatically as the
last step of the server installation.
A new switch has been added to be able to turn firewalld configuration off:
ipaserver_no_firewalld. It defaults to no.
The client role is used also while installing the server. There has been an
issue where the server installation has not been complete because of a
playbook termination in the client.
This has been fixed and the client and also the server are fully configured
in the server installation.
forward_policy needs to be None for the DNS check for proper initialization
if the user is not providing another forward_policy value. forward_policy will
be set in the DNS check.
no_dnssec_validation is enabled in the DNS check if the forwarders do not
provide DNSSEC validation. Therefore this needs to be handed over to the dns
installation later on.
New return values for forward_policy and no_dnssec_validation have been added
to the ipaserver_test module.
These global variables are initialized in the dns module in the
dns.install_check function. The settings are needed to be able to do a
proper dns setup in the ipaserver_setup_dns ansible module.
