options.kasp_db_file is used in dns.install_check if options.dnssec_master
is enabled. kasp_db_file defauts to None and is only a supported option in
the post deployment ipa-dns-install script. Therefore it is suffient to
set it to None.

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.

Currently only contains the ansible requirement: ansible>=2.4.1.0

With FreeIPA 4.5 the functions save_state and configure_nisdomain have gotten
new options. A version check has been added to ipaextras and ipanss to make
sure that the modules are also working with FreeIPA 4.4.

The roles ipaconf, krb5 and sssd have been using GPLv2+ in the license meta
information while everything else is GPLv3. Therefore the license meta
information has been changed to GPLv3.

force and allow_zone_overlap options were missing from a couple places.

This is needed to fix the installation without configuring the dns server in
the IPA server.

The relative import of the distribution specific vars files requires to use
is not working. {{ role_path }} needs to be used to force the load of the
proper files.

The server role has different setting names:

- groups.ipaserver: groups.ipaservers
- ipaserver_domain: ipaclient_domain
- ipaserver_realm: ipaclient_realm

Both need to be supported to be able to sue the client role within the server
role, but also standalone.

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.

The client settings are:

ipaclient_mkhomedir
ipaclient_no_ntp
ipaclient_ssh_trust_dns
ipaclient_no_ssh
ipaclient_no_sshd
ipaclient_no_dns_sshfp

ipaserver_password has been renamed to ipaadmin_password
ipaserver_dm_password has been renamed to ipadm_password

With using the name password for the password return it will be hidden
automatically and an error message will still be visible.

There is no way to repair a server installation like it is possible with a
client.

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.

This methods creates a list of ipautil.CheckedIPAddress from the provided
ip string list.
